CHAPTER 4 TONALITY 4.0 Introduction: recapitulation The phonological units of English Intonation can be represented on a hierarchical rank scale in descending order as: Tone group ---> foot ---> syllable and phoneme. The tone group is the highest ranked unit and it consists of one or more feet. A foot in tum consists of one or more syllables and so on. Thus each tone group consists of one or of more than one complete foot and so on throughout. The foot has been described as the unit of rhythm in English which has a structure of two elements. 'ictus' and 'remiss'. in that sequence. Each ictus begins a new foot. The unit below the foot is the syllable, displaying the two primary classes 'salient' and 'weak': the salient syllable operates at 'ictus' and the weak syllable at 'remiss'. The salient syllable or ictus is the obligatory unit while the remiss is the optional unit in a foot. Every foot therefore contains the element 'ictus' which may however be silent (have zero exponent) if the foot follows a pause or has initial position in the tonegroup. A foot with non-silent ictus is referred to as a 'complete foot'. Not every foot contains the element 'remiss'. Thus each foot consists of one salient syllable, either alone or followed by one or more weak syllables; in addition a foot that is tone-group initial may consist of weak syllable(s) only (with a silent ictus). The foot is characterized by phonological isochronicity: there is a tendency for salient syllables to occur at roughly regular intervals of time whatever the number of weak syllables in between. 4.1 The Tone Group (or Tone Unit) It is thus the foot which operates in the structure of the tone group. Like the foot. the tone group also comprises two elements of structure: these are "tonic" and "pretonic". The element "tonic" is obligatory: it is present in every tone group; the element 'pretonic' is optional. it mayor may not be present. If the pretonic is present it always precedes the tonic. A tone group contains a pretonic if. and only if. there is at least one 60 foot with ictus not zero (i.e. at least one salient syllable) before the beginning of the tonic. In other words. each simple tone group consists of a tonic or tonic segment. which extends from the tonic syllable right up to the end of the tone group and this mayor may not be preceded by a pretonic or pretonic segment. For example in II everybody I seems to have I gone away on I holiday II The tonic begins on the first syllable and extends over the whole tone group; there is no pretonic. On the other hand in II Jane may be I going on I holiday at the I end of the month II The first two feet form a pretonic segment and the remainder forms the tonic segment. The compound tone group has a double tonic that is. two tonic segments. one following immediately after the other. For example, II Robert can I have it if I you don't I want it II where the first tonic begins at Robert and the second at you. Compound tone groups may have only one pretonic segment and it precedes both tonics. For example IIArthur and I Jane may be I late with I all this I rain we're having II which has pretonic, Arthur and Jane may be, first tonic segment, late with all this and second tonic segment, rain we're having. No pretonic segment can come in between two tonic segments of a compound tone group. If they were merely sequences of two (simple) tone groups. each would be able to have its own pretonic segment. Each segment whether tonic or pretonic must consists of at least one complete foot. There may be only one foot in any segment but there must be at least one foot with a salient syllable in it. For ego II A it's I Arthur II 61 There is no pretonic segment here even through the tonic begins at Arthur; there is no salient syllable before the tonic. The syllable it's in this case could be regarded as a foot with a silent beat (which stands for the 'ictus'). The structure of a Tone Unit: Tone Unit Structure ) [ +pretonic ~ IpretOniC A Tonic I -pretonic Halliday therefore points out, "in any utterance in English three distinct meaningful choices or sets of choices, are made which can be, and usually are, subsumed under the single heading of "intonation". These are: first, the distribution into tone groups - the number and location of the tone group boundaries; second, the placing of the tonic syllable (in "double tonic" tone groups, the two tonic syllables) - the location, in each tone group. of 'the pretonic and tonic sections; third, the choice of primary and secondary tone. I propose to call these three systems "tonality", "tonicity" and "tone". The three selections are independent of one another." (1967: 18) 4.2 Internal Structure of a Tone Unit David Crystal (1969) talks of the internal structure of the tone unit in terms of pre- head, head. nucleus and tail. The pre head or pre-onset refers to any utterance which precedes the onset syllable within the same tone-unit. It consists of an unspecified number of unstressed syllables (at least one) but occasionally, under certain conditions, syllables with some slight degree of stress (not equivalent to the stress of the onset syllable and never with pitch prominence) may occur there. The head of the unit refers to the stretch of utterance extending from the first stressed and usually pitch-prominent syllable (or onset) up to but not including. the nuclear tone. It consists of at least one stressed syllable and an unspecified number of unstressed syllables. The nucleus is the obligatory element in the tone unit which carries a glide of a particular kind. Halliday uses the term 'tonic' syllable instead. The tailor nuclear tail may consist of an unspecified number of stressed or unstressed 62 syllables following the nuclear syllable usually continuing the pitch movement unbrokenly until the end of the tone-unit. We may now make a characterization of a tone-unit's maximal internal structure as being: (Prehead) (Head) Nucleus (Tail) the only obligatory element being the item in bold. The majority of tone-units tend towards this maximal type. Gimson (1962) uses the term intonational phrase to refer to a word group, which is called a tone group by Halliday. According to Gimson, the boundaries between these intonational phrases generally correspond with clause and major phrase boundaries and are indicated by a combination of internal and external factors. The external factor being a pause which can occur at the point where the boundaries are indicated by a[ IJ. Often as an alternative to pause. speakers may lengthen the final syllable before the boundary or increase the speed of the unaccented syllables following the boundary. The external cues to boundaries are supported by internal factors like the completion of a pitch pattern associated with a nuclear tone and a rapid change of pitch height of unaccented syllables. Therefore different linguists have used different terms to refer to the chunks of our speech. Spoken English is not a continuous stretch of utterance but is made up of a succession of tone groups. Each tone group is a unit of information according to Halliday. The speaker decides how he wants to break up the message -unconsciously, of course-into blocks or units of information and each of these is expressed as one tone group. Tone group or tonality deals with the chunking of a message into larger or smaller unit of information. In the Lexicogramatical stratum an information unit l is a stretch of language structured in terms of given and new. In the phonological stratum, the tone unit is more or less the same stretch of language structured in terms of (Pretonic) A Tonic. Therefore the system of tonality deals with how a long stretch of Lexicogrammar is 'chunked' by intonation. I In Halliday"s description "infonnation unit" <lnd 'tone group' are synonymou:-. terms. 63 According to Paul Tench, " ... tonality is the system by which a stretch of spoken text is segmented into a series of discrete units of intonation which correspond to the speaker's perception of pieces (or 'chunks') of information ... " (1996:8). We chunk our utterances to give bits of information depending on grammar, meaning, context, communication and the textual function of tonality. 4.3 Criteria for Marking Tone Group Boundary Crystal (1969) identifies both phonetics cues and the internal structure of the tone unit as criteria for boundary location. He says, " .. .internal information. along with the phonetic information about boundary characteristics which is essential, is sufficient to resolve any doubts over tone-unit identification in English" (1969:208). He says that each tone-unit will have one peak of prominence in the form of a nuclear pitch movement, then after this nuclear tone there will be tone-unit boundary which is indicated by two phonetic factors. There will firstly be a perceivable pitch-change, either stepping up or stepping down, depending on the direction of nuclear tone movement- if falling than step-up; if rising, then step-down; if level. either depending on its relative height, either a stepping up or down would signal the start of a new intonation unit. This is due to the fact that the onset of each tone-unit in a speaker's utterance is at more or less the same pitch-level. The second criterion is the presence of junctural features at the end of every tone-unit. This usually takes the form of a very slight pause but there are frequently accompanying segmental phonetic modifications (variations in length, aspiration. etc) which reinforce this. Syllables at the end of a unit tend to be relatively slower, but syllables at the beginning of a unit have a tendency to speed up. Very often all three features; a change of pitch. a pause and a change of pace or anyone feature may be present. The marking of the tone group boundary has been most controversial in Halliday's description of tonality. He says ... m any case it must be insisted that the location of the tone group boundary is a theoretical decision: the best description is obtained if a new tone group is considered to begin at the foot boundary immediately 64 preceding the first salient syllable of its tonic or pretonic, as the case may be. But what matters is that the boundary between any two tone groups can be shown to lie within certain limits, so that it is clear how many tone groups there are in any stretch of utterance ... Halliday (1967: 19 foot note) The best decision would therefore be to mark a tone group at a foot boundary. Cruttenden (1986) says that an intonation-group boundary should be based on 'external criteria'. i.e. on phonetic cues present at the actual boundary. But in practice such phonetic cues (e.g. pause) may be either ambiguous or not present at aIL Therefore 'internal criteria' must also playa part: ... he says that The assignment of intonation-group boundaries is therefore something of a circular business; we establish some intonation-groups in cases where all the external criteria conspire to make the assignment of a boundary relatively certain ... Cruttenden (1986: 36) He also says And in some difficult cases. we take grammatical or semantic criteria into account, i.e. when regular correspondences between intonation and grammar/semantics have been established in cases where boundary assignment is clear. .. Cruttenden (1986: 36) Cruttenden mentions 'pause' which is the usual criterion m the demarcation of intonation-groups. The forms of pause fall into two categories. the unfilled pause (i.e. silence) and the filled pause. In R.P. and in many other dialects of English. the filled pause involves the use of a central vowel l;l J and a bilabial nasal I m J. either singly or 65 in combination and of varying lengths. The use of pause in general and the relationship between unfilled and filled pauses in particular is subject to a large amount of idiosyncratic variation. He also mentions the fact that breaths are often taken at pauses and taking of breath is the reason for pausing. He talks of three places where pauses occur in utterances. They are: (i) at major constituent boundaries (principally between clauses and between subject and predicate). There is a correlation between the type of constituent boundary and the length of pause. i.e. the more major the boundary, the longer the pause. Moreover, pauses tend to be longer where constituent boundaries (usually, in this case sentence boundaries) involve a new topic. (ii) Before words of high lexical content or. putting it In terms of information theory, at points of low transitional probability. So words preceded by a pause are often difficult to guess in advance. This sort of pause typically occurs before a minor constituent boundary, generally within a noun-phrase, verb-phrase. or adverbial-phrase, e.g. between a determiner and following head noun; (iii) after the first word in an intonation-group. This is a typical position for other 'errors of performance', e.g. corrections of false starts and repetitions. (1986: 37) Pause type (i) is generally to be taken as indicating an intonation-group boundary. e.g. {boundaries are indicated by [/]}. Although this type of pause will be unfilled but sometimes it may be filled and in such cases the filling seems to be used as a tumkeeping device, particularly in conversation. It is used to prevent another potential speaker interrupting the current speaker. Pause types (ii) and (iii) are generally to be taken as examples of hesitation phenomena. Type (ii) indicates a word-finding difficulty. e.g. (hesitation pause indicated by .... ). 66 e.g. The Minister talked at length about the ... redeployment of LABOUR. The hesitation pause of type (ii) will occur before a word of low transitional probability although it is unlikely before a word carrying the nucleus of the intonationgroup in which it occurs. Pause type (iii) occurring after the first word of an intonation group. seems to serve a planning function i.e. it is essentially a holding operation while the speaker plans the remainder of the sentence, i.e. e.g. Why don't you join an evening class? You'd ... be quite likely to meet some interesting people Pause types (ii) and (iii) are internal to an intonation group, and are not taken as markers of intonation-group boundaries, because they do not result in utterance chunks each of which has a pitch pattern within an intonation-group. Cruttenden also says that a better system for measuring pause may be to relate it to the length of syllables or rhythm groups in surrounding speech. Whichever way of measuring is used, boundary pauses tend to be longer than hesitation pauses. It is therefore apparent that the criterion of pause as a marker of intonation-group boundaries cannot be used on its own. Pause can only be used as a criterion if it is considered together with other external and internal criteria. (1986: 38-39) Apart from pause, Cruttenden talks about three other external criteria which may act as markers of intonation-group boundaries. They are firstly, the presence of an anacrusis which generally indicates the beginning of an intonation-group, e.g. I saw John yesterday I and he was just off to London. In this sentence. the most likely place for the first stress in the second intonation-group is on JUST: and the unstressed syllables before "just' are pronounced very quickly than other unstressed s yl\ables in the sentence. The sudden increase of speed beginning at 67 'and' indicates that these syllables are anacrustic and hence that it is the beginning of a new intonation-group. Secondly, and regardless of whether it is stressed or unstressed, the final syllable in an intonation-group will often be lengthened, e.g. On my way to the station / I met a man. The second syllable station may be lengthened and this helps to indicate an intonationgroup boundary. The lengthening may be a by-product of two other things occurring at an intonation-group boundary: it may be a sort of pause-substitute, as a sort of filled pause. The final syllable of an intonation-group will often carry a final pitch movement. The clearest function for final syllable lengthening is therefore as a boundary marker, sometimes replacing pause and sometimes in addition to pause. But he then says that the three criteria for intonation-group boundaries (pause, anacrusis and final syllable lengthening) all are ambiguous between boundary marking and hesitation phenomena. The last external criterion concerns the pitch of unaccented syllables. Changes of pitch level and pitch direction most frequently occur on accented syllables. A change in pitch level among unaccented syllables is generally an indicator of an intonation-group boundary. (i) After falling tones followed by low unaccented syllables, there will be a slight step-up to the pitch level of the unaccented syllables at the beginning of a new intonation-group. The change of pitch reflects the fact that low unaccented syllables at the beginning of an intonationgroup are generally at a higher level than low unaccented syllables at the end of an intonation group. (ii) Following rising tones there will be a step-down to the pitch level of any unaccented syllables at the beginning of the following intonationgroup. So a change in the pitch of unaccented syllables is a fairly clear boundary marker. (1986: 40-41 ) 68 Cruttenden lays more importance on the presence or absence of a likely internal structure for an intonation-group as he considers that the external criteria which he mentions are ambiguous between boundary and hesitation marking. He talks about two internal criteria which characterize an intonation-group (i) that an intonation-group must contain at least one stressed syllable. (ii) there must be a pitch movement to or from at least one accented syllable. He finally summarizes that one or both of the following criteria will in most cases help to mark intonation-group boundaries. They are (i) change of pitch level or pitch direction of unaccented syllables (ii) pause. and / or anacrusis, and / or final syllable lengthening, plus the presence of a pitch accent in each part - utterance thus created. (1986: 42) Cruttenden also talks about three types of pitch sequence which present problems for dividing utterances into intonation-groups in English. He gives the example of a sentence: J. He went away unfortunately • • .~ • ••• • We have a falling tone starting on- way and a rising tone starting on- fort with an anacrusis on- un- intervening between them. The problem here is. are we to analyse this pattern as consisting of one or two intonation-groups. In terms of the external criteria discussed above if there is a pause, or anacrusis on- un or syllable lengthening of- way. it must be treated as two intonation-groups as there is a pitch accent in each half. It must also be taken as two groups if the syllable un- is on a slightly higher pitch than the end point of the tone on- way. But frequently none of these patterns will be present and thus by phonetic criteria alone we would have to consider the pattern as one group. 69 However, he suggests that in such cases, we can take syntactic or semantic factors into account. He says In this type of pattern it seems reasonable to take account of the fact that markers of a boundary frequently are present between final 'sentence' adverbials and what precedes them and to regard the 'basic' intonation as involving two groups. present, can The pattern above, where no markers are accordingly be considered a special instance of INTONATIONAL SANDHI. (1986: 43) Sandhi ('sandhi' was used by the ancient Indian Grammarians) means joining together and indicates the merging of two basically independent intonation-groups. 2. The second problematic case concerns vocatives and reporting clauses In sentence final position. For example - Get a moye on. you stupid fool • • • •• • • This kind of utterance has been analysed as having a low level tone within a separate intonation-group, since a pause is often present before the vocative or reporting clause. But Cruttenden says that... such sequences consist of one group only, whether pause is present or not, on the grounds that there is no pitch accent in the vocative or reporting clause (1986: 44). 3. The third problematic case concerns instances where an adverbial on a low pitch may belong semantically either with the words in the preceding intonation-group or with the words in the following intonation-group. example - 70 For ...... He went to the States of course he didn't stay very long • • • • • • ~ (In this example, punctuation marks have been deliberately avoided) Here the low pitched of course could belong either with what precedes or what follows. In this example, either the three syllables of course he are just above the lowest pitch and hence characteristic of beginning pitch rather than end pitch, in which case there is a boundary before of. or else the two syllables of course might be at the lowest pitch with he occupying a slight step-up, in which case the boundary would be between course and he. Cruttenden considers that the three problematic cases discussed above show that the concept of intonation-group is like many other units of linguistic analysis, essentially a theoretical construct. (1986: 44) Brown, Currie and Kenworthy (1980) analysed spontaneous speech and although they found Crystal very explicit, they expressed their difficulty in identifying the tone group boundaries. They faced two types of problems (i) Absence of pause in stretches of speech which have more than one nucleus (ii) Presence of pause where "the overall pitch contour appears to be carried on through this pause". Therefore, they prefer to work with pause-defined (1980: 43) units rather than toneunits. Their problems could be resolved (i) In case of absence of pause by - the association of the foot boundary with the tone group boundary and the identification of the tonic syllables and the tones operating in them which will help in locating the boundaries in most cases. (ii) In case of presence of pause by - the recognition of the role of silent ictus in the foot and the presence of silent feet in speech. 71 Pike (1945) says that phonological units do have 'fuzzy edges', for instance, how do we identify, the boundaries of consonants and vowels, especially in the light of instrumental evidence of continual overlap. Some linguists have maintained that it is not absolutely necessary to identify tone boundaries precisely. There is often also a smooth transition from one tone unit to another without a pause. Halliday has incorporated this aspect into his work by talking of compound tones: a fall followed by a rise etc. When cases of dispute are difficult to resolve, we have to take the help of grammatical or semantic criteria. 4.4 Identification of Tone Group Boundaries in AE The system of tonality performs the textual metafunction of language by dividing the message into smaller chunks which are called information units by Halliday. The other two metafunctions of construing experience and enacting interpersonal relations depend on being able to build up sequence of discourse, organize the discursive flow, create cohesion and continuing of the discourse. The criteria for identifying Tone Group boundaries m this study were based on auditory as well as instrumental evidence. The study revealed the following eight cues for marking tone group boundaries: (refer to Appendix IV) 1. Tonic prominence 6. Change in pitch direction 2. Pause 7. Pitch jump up or jump down at the onset of a new TG 3. Lengthening of last syllable 8. Anacrusis 4. Foot boundary coinciding with tone group boundary 5. Silent ictus beginning a tone group However, the frequently occurring cues found were· tonic prominence, pause, pitch jump up or jump down and change in pitch direction. 1. Tonic Prominence Tonic Prominence is the identification of the tonic syllable in the tone group and it is one of the important cues for the identification of the TG boundary. It carries the main burden of the pitch movement in the tone group.The tonic syllable is heard longer and louder than the other salient syllables in the tone group. it plays the principal part in the 72 tone group. It covers the widest pitch range. A tone group will have one tonic syllable which generally occurs as the New focus of information placed at the end of the tone group. For example: 120Hz·400Hz 1/2 from I then II have Istopped /SlKGing II Speaker HD20LA (tonic prominence) Clause(s) from then I have stopped singing. TGs //2 from I then I I have I stopped I SINGing II 2. Pause In this study three types of pauses were identified i.e. I. 11. 111. significant pause insignificant pause filled pause The pause may be due to several factors such as hesitation, difficulty in finding appropriate words, placing of grammatical words and structures such as adjuncts, adverbials. noun phrases etc. and the tempo of the speaker, which is a variable idiosyncratic feature. i. Significant Pause The duration of the pause is a significant indicator of tone group boundary. The following example (speaker: DB I UA) shows significant pause indicating TG boundaries between TGs. 73 90Hz-300Hz //2 the/oxygen of the/water / body /recei;VING// Speaker DBIUA (significant pause) Clause(s) thus. the oxygen of the water body receiving TG /II THUSI/2 the! oxygen of the! water! body! recei ! VING 1/ There is significant pause after thus and before the beginning of the next TG. Significant pause was used with grammatical categories as well as between two regular clauses marking them separate TGs, it could also be observed in free speech, may be due to the difficulty of the speakers in finding proper words to continue their speech thus often breaking a regular clause into TGs. ; ACtiyiti ) Speaker DD I 3MA (significant pause) Clause(s) and I like to perform some social activities. TG 1/ I AND 1/ 2 i! LIKE 1/ 2 to! perform! SOME 1/ I social! Activities 1/ In the example above significant pause divides a clause into several TGs. 74 ii. Insignificant Pause The duration of the pause is not significant, yet it clearly marks a tone group boundary perceived auditorily as well as from other internal cues like tonic prominence etc. lJ-- ..- - - - - . - - - - - - - - - - - ... - - - -.. 50Hz-280Hz !

TG II I SPLENdid II I what a I beautiful I SIGHT II No significant pause can be observed after Splendid. But the presence of tonic prominence and pitch direction are cues suggesting a definite TG boundary. 50Hz-350Hz / /1 like ! In I DIAl I I/R-F in / DEVeloping,l COll'triesj / Speaker NDI5LA (insignificant pause) Clause (s) in developing countries like India TG II R+F in I DEVeloping I COUN tries II I like I In I DIA II The pause between the TGs is insignificant but the change in the direction of the pitch and the tonics in the TGs identify the TGs. 75 iii. Filled Pause A filled pause is filled with sounds like -aa ... ; 1..1.. etc. It may be just a variable idiosyncratic feature of the speakers. Some of the speakers tend to use filled pauses more frequently than others due to their inability to find proper structures to continue and to find time to relate their thoughts to their speech. It is noticed that a filled pause marks the beginning of a new TG boundary. 50Hz-300Hz 112 aa~./my /FAmily / I II 3 aa~ ~/consist of/four / mom / BER/ / Speaker: DNIOMA (filled pause) Clause(s): my family consist of four member. TG: //2 aa .. I my I FAmily //3 aa .. consist of I four I mem I BER // In the example above, the speaker uses filled pause at the beginning of both the TGs. thus clearly marking the tone groups. e.. she's is aa. 50Hz-350Hz 1(2 e.. I SHE'S/ / aa .. ;' /2 going to / fi / Speaker: RDI9LA (filled pause) Clause(s): and she's going to finish 76 ~lSH/ / TGs: /I 2 e .. / SHE'S /I aa .. /I 2 going to / fi / NISH /I The filled pause in the above example occur between two TGs. 3. Lengthening of the Last Syllable The length of the final syllable of a tone group was found to be comparatively longer than the other syllables of that tone group. This lengthening of the final syllable in a tone group was an indication of a tone group boundary in some cases, for example: and my wife is a good house \\ife 60Hz·200Hz / /) and,l Illy / wife I IS/I / /2 a / good / house / Speaker: HN9MA (lengthening of last syllable) Sentence: and my wife is a good house wife TGs: /II and my / wife / IS II 2 a / good / house / WIFE /I In the above example the last syllable 'is' of the lSI TG is lengthened marking the end of the TG and the beginning of a new TG. 70Hz·200Hz / iL and/HIS; / / I I major/sub I jeet is / .-\SSamese / / Speaker: CG3UA (lengthening of last syllable) Clause(s): and his major subject is Assamese TGs: /I Land / HIS /I I major / sub / jeet is / ASSamese II 77 In this example the last syllable 'his' of the first TG is lengthened marking the end of the TG and the beginning of the following TG. 4. Foot Boundary Coinciding with TG Boundary According to Halliday the best decision for marking tone group boundary would be at a foot boundary. This criterion has been observed in this study also as is evident from the following example. /_ 2 take / LIST / __ -.L_ _/_ _ _/_this __ _ _/_ Speaker ~ ____ ~ / /_2gotothe __ _ _ _ _/_GROcery/ _ _ _ _I_ _ ~· /01 JNCIIMA (Foot boundary coinciding with TG boundary and tonic prominence) Clause(s) take this list, go to the grocery TGs 112 take I this I LIST 1/2 go to the I GROcery 1/ In the above example, the TG boundaries coincide with foot boundaries. 5. Silent Ictus Beginning a Tone Group A foot may begin with a silent beat which has no phonetic realization like a musical bar beginning with a rest. In English a tone group may begin with a silent ictus with weak syllables optionally following it in a foot. A silent ictus is clearly perceived before a significant pause beginning a foot in a tone group. 78 •. I",,",," l ,\ J " i, " Thus //FRffiUS// Speaker NNRI4LA (silent ictus beginning a tone group) Sentence Thus the oxygen of the water body TGs II FR THUS II F+R A the I oxy I GEN of the I waterl bo I DY II In the above example, the silent ictus marks the beginning of a new foot in a tone group, 6. Change in Pitch Direction Marking a Tone Group Change in the pitch direction of the tonic, for example from a nsmg to a falling direction indicates the beginning of a new tone group, Speaker PH4UA (change in pitch direction and silent ictus in foot marking a new tone group) Clause(s) It's pleasant today. is not it? TGs II 2 A It's I PLEAsant II I to I DAY //2 A is I not I IT // In the example above, the first tonic has a rising tone while the second tonic has a falling tone showing opposite pitch directions, Similarly the third tonic has a rising movement indicating a new tone group, All the three TGs project contrasting pitch directions, 79 7. Pitch Jump Up or Jump Down A pitch jump up or a pitch jump down indicates a tone group boundary. For a falling tone there would be a slight or significant jump up to make the fall, and for a rising tone there would be a jump down in the pitch to make the rise in the tonic. These are important factors in identifying tone groups. 70Hz-250Hz J;2 GEORGE;! 1/2 willi yOU! get the; C\R OUl/ / Speaker HN9MA (Pitch jump down at the onset of a new tone group) Clause(s) Will you get the car out, George. TGs 112 willI you I get the I CAR out II 2 GEORGE II In the above example there is a clear jump down in the pitch direction after the first tonic to enable a rise in the second tonic in the new tone group.

Anacrusis A tone group may begin with a foot with unstressed syllables uttered quickly; these unstressed syllables are anacrustic and is an indication of the beginning of a tone group. These syllables uttered with sudden increase of speed usually begin with a silent ictus. ' - _ _ _ _ _ _ _1'-'1_2_,_,w_e_d_o_h_,,_e.:./=.good_.:./_e~--,-p_~_a,--I_TI_O_"'..:/..:./_ _ _ _ _ _ _...L.l . .'"'<) Speaker CG3UA (anacrusis) Clause(s) we do have good cooperation. TG 1/ 2 1\ we do have I good I coopera I TION 1/ In the above example the first three syllables 'we do have' of the tone group are uttered quickly in 0.4 I 3s. with an average of 0.137s. which is much quicker than the speed with which the other syllables are uttered. This study has also revealed that the speakers made separate tone groups for listing items; vocatives. inteIjections, responses, conjunctions, interpolations, adverbials, a long subject, comment adjuncts and conditionals. Speaker NB2UA (listing items indicating TGs) Clause(s) would you like to have tea. coffee or juice, TGs 1/ 2 would you I like to I have I TEA 1/ 2 Coffee 1/ 2 1\ or I JUICE 1/ In the above example. the listing items tea, coffee. juice are said as separate tone groups. 81 Speaker RS8MA (V ocati ve said as a separate tone group) Clause(s) Its no good Mary.

The clause is the most obvious unit of grammar to handle a piece of information. Halliday has tried to establish a relationship between a tone group and a grammatical unit. He says It has sometimes been suggested that the division of an utterance into tone groups is congruent with its division into grammatical units. There is no agreement, however, as to which of the grammatical units is co-extensive with one tone group; and this is not surprising, since in fact the tone group bears no fixed relation to any of the grammatical units of spoken English. There is a tendency for the tone group to correspond in extent with the clause; we may take advantage of this tendency by regarding the selection of one complete tone group for one complete clause as the neutral term in the first of the three systems. That is to say, a clause which consists of one and only one complete tone group will be regarded as 'neutral in tonality.' Halliday (1967: 18-19) Tench (1996) has mentioned thatthe concept of neutral tonality is a very useful starting-point. It embraces a very important point: the functional equivalence of intonation unit. clause and unit of information. linking up phonology with grammar and semantics. Tench (1996: 33) 85 The tenn 'neutral tonalitl' is considered synonymous with 'unmarked tonality' by both Halliday and Tench. Marked tonality is any case that does not correspond to neutral tonality. It occurs either when two or more clauses fit into a single intonation unit or when two or more intonation units are needed to cover a single clause. Examples of unmarked tonality are I. II A dog is a man's best friend /I 2. /I He spoke to me honestly /I Examples of marked tonality are I. /I He did. I saw it /I 2. /I We need milk /I some bread /I and butter /I Halliday (1967, 1970 and 1994) identifies two options for a speaker(i) he may select a clause to fonn one tone group - unmarked tonality. (ii) he may select more than one clause as one tone group or less than one clause as one tone group - (these are two marked possibilities). These two selections of unmarked and marked tonality can be represented also as follows: (one tone group = one clause) Unmarked Tonality one tone group is less than a clause Marked [ one tone group is more than a clause (Bhooshan 1998: 15) Halliday says, marked tonality. where the tone group is more than a clause arises in two types of sentences (actually sequences of elements of sentence structure linked by presupposition): (i) reporting clause followed by reported clause and (ii) conditioned clause followed by conditioning clause. : \Ve have u\ed these two terms: neulml and unmarked Tonality jnten:hange<lbl~ in our study. 86 /I:!:" but I I don't see I why they should lose I marks for I this /I /I :!: " it's I all right if you're I photo I ~nic /I I what I happens if you're I not /I (ii) If a conditioning clause precedes the conditioned clause which it presupposes, the two may still sometimes share a single tone group; sentences of this structure have neutral tonality, with a tendency for all clauses except the last to select tone 4. /I 4 " and and Isince the Icredit mark is a I hundred /I I +" you I couldn't very weill mark out of a I hundred /I In the sequence of conditioned - conditioning clause, there may be neutral tonality: /I I " per I haps it's I easier when you're /I I marking I language /I Relative clauses do not take a separate tone group in general while a non-defining relative clause (additioning clause) take a separate tone group and is consistent with neutral tonality. This is because relative clauses are rank shifted and do not operate in sentence structure, whereas additioning clauses are not rank shifted and so do enter into the sentence structure. /I I " in I fact you I end I up with a I pure I culture of I something you I didn't! start with /I compared with /I I " I'm I marking a I thousand .. .11 4 " of which I three are from I home centres and ... // (Examples taken from Halliday 1967: 20-21) In the case of marked tonality. where the tone group is less than a clause, it occurs mainly with the break (into two tone groups) coming after the first element of clause structure. that is. the first element that contains a lexical item. The break occurs after the theme. Halliday mentions other possibilities where a break occurs (i) break after unmarked theme /I :!: all the I dialect forms are /I I + marked I wrong II 87 (ii) break after marked theme 111 1\ but I in A I merica they they /I I !l!yer I things /I (iii) break other than after theme /I 1 1\ they can I change I overnight I then /I I 1\ into I something comlpletelyl different /I (please refer to chapter 6 for the symbols used for the tones in these examples) He also mentions that a break other than after the theme is most commonly found immediately before a clause - final adjunct, as in the above example. To sum up, neutral tonality refers to the selection of one clause to from one tone group and this clause may contain within it embedded clauses or rank -shifted clauses i.e. a defining relative clause. Trench (1996) discusses instances of marked tonality: I. Two clauses may fit into a single intonation unit as in /I He did. I saw it /I 2. A clause may be said in a single intonation unit as /I He spoke to me honestly 1/- (neutral case) or the clause may be broken into separate units; /I He spoke to me /I honestlyl/- (marked case) 3. He talks of lists. A list is a special kind of long clause and each item is treated in a separate unit. All the intonation units are marked instances as they are less than a clause. /I We want red /I white II and blue flags please /I 4. Marked theme - This is an instance of deviation to the structure of a clause where a clause element precedes the subject and that element becomes the theme. instead of the subject. If anything precedes the subject, then that takes over the role of theme and such cases of marked theme always have a separate intonation unit as they are cases where a tone group is less than a clause. /I Last night 1/ you came in too late /I 88 But a marked theme can also have a neutral tonality as in the following. e.g II If you go out in the evening II I want you in by eleven II Here each clause, the dependent clause and the main clause has its own intonation unit. 5. Adjuncts - Addition of certain kinds of adjuncts either at the beginning or in the middle of a clause can be instances of separate tone groups. If these adjuncts appear at the end of the clause, they may either have an intonation unit of their own or be incorporated into the preceding clause. Adjuncts that affect tonality are linking adjuncts like however, nevertheless. perhaps, of course, unfortunately, etc. II He ran the mile II however II in four minutesll Vocatives also take separate intonation units likeII Miss Smith I can you come with me II 6. Tags - Tags generally have their own intonation unit. but we can make a distinction between checking tags and copy tags. Checking tags, i.e. those with reverse polarity have a separate intonation unit as they are separate clauses and are cases of neutral tonality. II John's going out II isn't hell Copy tags, i.e. those with identical polarity, do not necessarily require a separate intonation unit if it forms a part of a falling tone. It will then be a case of marked tonality as the intonation group will be more than a clause. Checking tags can however be accompanied by either a falling or a rising tone with a change of meaning. Copy tags accompanied by a rising tone will form separate intonation units. II John's going out II i!! he II - neutral tonality (Rising tone) II John going out is he II - marked tonality (Falling tone) Tench (1996) has also observed that intonation units have an average of between two and three feet each i.e. two or three word stresses. The usual maximum number of stresses in an intonation unit is fIve and this corresponds to the maximum number of 89 elements in a single simple clause: subject, verb, direct object, indirect object and adjunct, e.g. /I The 'office 'sends the 'students their' grants in Oc'tober II This sentence can be said as one unit of intonation or one unit of information but it reaches the maximum of five feet, if a clause breaches that maximum number it is automatically converted into two or even more intonation units. 4.6 Instances of Marked and Neutral Tonality in AE Instances of Neutral and Marked Tonality have been found in the following selections in this study I.

The theory specifies that a speaker-s 99 perception of their organization of information is in the form of a single unit of intonation, which is typically within a single clause. So where there is a congruence of semantic, phonological and grammatical units, tonality is neutral where there is not, tonality is said to be marked. 4.7 Role of Tonality in the Information Function of Intonation Halliday (1967) refers to Information Distribution where one information unit in a TG IS tonality neutral; /I I saw John yesterday II breaking up a TG into two information units is tonality marked; /I I saw John II yesterday II The system of information distribution can be represented also as: Inform~ distribution -~ Unmarked (conflated with a clause) Marked (conflated with anything else) The distribution of information is unmarked if the information unit is conflated with a clause. Information distribution is marked if it is conflated with any other grammatical unit. Tench (1996) also talks about tonality in relation to the informational function of intonation. He relates tonality with grammatical structures to show that changes in tonality brings about changes in the information distribution as is mentioned in the following I. Defining and non-defining items: I. 1/ My brother who lives in Nairobi II ... and II. II My brother /1 who lives in Nairobi /I ... 100 In the first instance (i) the relative clause defines which brother is meant, it restricts the reference to mean not the brother living anywhere else. In the second instance (ii) the relative clause does not define the brother but only adds extra information i.e. it does not restrict the reference. This type of adding clauses or non-defining clauses are singled by the tone group boundary after the subject. In another sentence like 1/ The man with the dog sitting near the bus stop II and 1/ The man with the dog /I sitting near the bus stop /I The first sentence suggests that it is the dog that is doing the sitting, as the sitting defines which dog is meant. The second sentence suggests that it is the man who is sitting near the bus stop. It is additional, non-defining information. The tone group boundary is performing a grammatical function and also affecting the meaning. 2. Apposition: Apposition is the relationship between two or more items which are either identical in reference or else the reference of one must be included in the reference of the other. In a sentence like Tom Jones, the singer, comes from South Wales. There is identity of reference between the two appositional items Tom Jones and the singer. The sentence can be said as /I Tom Jones the singer /I comes from South Wales /I the tone group boundary after singer identifies which Tom Jones is meant, since in South Wales there are hundreds of Tom Joneses. If the sentence is said as /I Tom Jones /I the singer 1/ comes from South Wales /I 101 in this case the singer is added as extra information. The distinction between defining and non-defining apposition is thus indicated by intonation in the spoken mode. Quirk et al. (1972: 626-7) cite three cases of potential ambiguity between instances of apposition and the more complicated types of complementation. The first example cited is II They sent Joan a waitress from the hotel II As a single intonation unit, the sentence would be interpreted as a waitress from the hotel being sent to Joan i.e. as a double transitive clause. Joan as an indirect object, a waitress from the hotel as direct object. If we put a tone group boundary after Joan, II They sent Joan II a waitress from the hotel II In this case, Joan is the waitress from the hotel. But if we add a second boundary after waitress, II They sent Joan II a waitress II from the hotel II The meaning here would be, Joan is still a waitress, but now she is sent away from the hotel. Tonality is doing both grammatical and informational work in this case. Apposition may take the form of clauses as well as noun phrases and in many cases clauses In apposition become relative clauses. Examples et aI., (1972: 645-8) I. II They put it where it was light II Where everybody could see it II 2. II He told them the news II that the troops would be leaving II These are cases of non-defining apposition. 102 from Quirk Apposition may also take the fonn of other clause elements like (i) Predicates (Examples from Quirk et.a\., (1972:645-8). /I They summoned help II called the police and fire brigade II (ii) Complements II She is better II very much better II (iii) Adjuncts II Thirdly II and lastly II they would not accept his promise /I 3. About Syntactic Structure: Different tone group boundaries affect the interpretation of syntactic structure. For e.g. II He died a happy man II (subject complement) II He died II a happy man II (apposition, implying 'he'd always been a happy man') 4. Verb Phrases: A verb phrase can be simple: with a single lexical verb; or complex: with more than one lexical verb. For e.g. (you must) try to stop smoking. Some complex verbal phrases look very similar to a series of verbs (i) He began smoking (ii) He began to smoke (iii) He stopped smoking (iv) II He stopped II to smoke II The (iii) and (iv) verbal phrases look as if parallel to the verbal phrases (i) and (ii). The pair (i) and (ii) have different structures but share broadly the same meaning. The verbal phrase (iii) is the opposite of (i) and (ii). The phrase in (iv) may look superficially the parallel to (ii) but have a different structure and meaning. In (iv) there are two simple verb phrases, the first belongs to a main clause and the second to the following purpose clause which when read as in order to smoke. will make the meaning clearer. As (iv) consists of two clauses. neutral tonality exists i.e. two clauses and so two tone groups. 103 In another example - (i) /I He left me to get on with the job /I and (ii) /I He left me II to get on with the job /I Sentence (i) has a single though complex, verbal phrase: one clause and one intonation unit whereas (ii) is a series of two clause i.e. main clause followed by a purpose clause, has two intonation units. The tone group divisions in each sentence have a difference in meaning too. 5. Negative domain: Tonality plays the crucial role of differentiating two syntactic structures and meaning in case where the main clause has a negative and is followed by because and a reason or by so (that) and a result. An utterance such as 'I didn't come because he told me', said as two intonation units with one clause each (neutral tonality) would make the meaning quite clear: the person did not come, and a reason for not coming is added: /I I didn't come /I because he told me /I If however the two clauses are uttered in a single intonation unit (marked tonality), implies: the person did go, but not for the reason that is given- he went for some other reason: /I I didn't come because he told me /I This seems to be the case that the domain of the negative extends to the next tonality boundary; thus in first sentence it is come that is negativized but in the second sentence it is because he told me that is negativized. Thus in the case of Marked Tonality, the negative IS transferred to the following clause. 6. Report clauses: In these clauses there is an initial verb of reporting and a clause containing the context of what is reported~ 104 The two parts are usually linked by a conjunction e.g. that, whether, if_but the that conjunction may be omitted. The two parts can be regarded as a single clause consisting of the main verb of reponing and a (rank shifted) clause as the direct object complementing the reporting verb. Even if the reponing verb is at the end, a single tone group is sufficient. e.g. II I reported that they had taken a decision II II They had taken a decision, I reported II The difference between report clauses and direct speech can be brought out by intonation. e.g. II He said he would come II - report clause II He said II I'll come II - direct speech Report clause structures with know can be distinguished from linking adjuncts like you know by tonality. II You know its important II and IIYou know II it's important II you know is acting as a means of linking a previous utterance with the new one in the following main clause. 7. Clause Complements: Intonation helps in distinguishing between transitive and intransitive verbs. (i) II She washed and brushed her hair II (ii) II She washed II and brushed her hair II In sentence (i) her hair is the direct object complementing both the verbs washed and brushed. thus washed (and brushed) is transitive. In sentence (ii) washed is intransitive, as the tone group boundary separates that verb from the other elements and hair is the direct object complementing brushed only. Here only brushed is transitive. The 105 meaning conveyed is 'she washed herself but not her hair'. Therefore intonation brings out a difference in meaning in these grammatical items. In another e.g. 1/ They've left 1/ the others 1/ In this case, the others is the 'real', but displaced, subject, conveying the meaning, 'the others have left (actually),. To leave is a verb which can be either intransitive or transiti ve as in 1/ They've left the Qthers 1/ In this case the others is the direct object complementing left. Intonation, therefore, brings out the grammatical difference. Regarding the functional equivalence between a tone group and an information unit, Halliday says that the tone group is a unit of information and the speaker decides how to break up the message into units of information but these units of information may not always contain much, in the way of information. Units may often contain exclamations like wow' , My goodness me! , I mean, you see, etc. Tench (1996) therefore feels that the term unit of information has to be defined relatively broadly: it is the semantico-phonological unit for the development of discourse, which handles not only information or propositional context but also markers of style, expressions of attitudes and feelings, 'running repairs' or 'phatic communion' like Good morning and How do you do? and politeness formulas like please, thank you and don't mention it. (Tench 1996:51) In this study the role of Information Structure is determined by certain grammatical criteria cited through worked out examples4 following below: L\ Please refer to Appendix II for the conte:x{ of the example~ 106 Example: 1 60Hz-200Hz / /1 which is/ one ofthejmain/SOCRces of,!,1 1 pollution of / WAter/I Speaker YR 16LA (Non-defining Relative Clause uttered in more than one Tone Group) Clause Which is one of the main sources of pollution of water TG(s) III which is lone of the I main I SOURces of II I pollution of I WAter II Example: 2 ... v.-!Uch uses oxygen for decomposition ;3) Speaker TG7UA (Defining Relative Clause in a TG) Clause which uses oxygen for decomposition TG III which I uses I oxygen I for I de I COMposition II 107 Example: 3 1/1 which; uses/oxy I GEN II I de/COMposition/ / Speaker NNRI4LA (Defining Relative Clause in more than one TG) Clause which uses oxygen for decomposition TGs 1/ I which I uses I oxy I GEN !II FOR 1/ I de I COMposition 1/ Example: 4. looHz·3ooHz /121"11 come/,,;th!

This erratic system of AE intonation: System of Tonality does not bring about distinct differences in meaning and grammar of these syntactic choices. This may lead to loss of information and impair intelligibility to a great extent. 116
