ngdon, J. OConnor, A. Gimson and others. It is traditional and widely used. According to this approach the smallest unit to which linguistic meaning can be attached is a tone-group (sense-group). Their theory is based on the assumption that intonation consists of basic functional "blocks". They pay much attention to these "blocks" but not to the way they are connected. Intonation is treated by them as a layer that is superimposed on the lexico-grammatical structure. In fact the aim of communication determines the intonation structure, not vice versa.grammatical approach to the study of intonation was worked out by M. Halliday. The main unit of intonation is a clause. Intonation is a complex of three systemic variables: tonality, tonicity and tone, which are connected with grammatical categories. Tonality marks the beginning and the end of a tone-group. Tonicity marks the focal point of each tone-group. Tone is the third unit in Hallidays system. Tones can be primary and secondary. They convey the attitude of the speaker. Hallydays theory is based on the syntactical function of intonation.founder of the American school of intonation K. Pike in his book "The Intonation of American English" considers "pitch phonemes" and "contours" to be the main units of intonation. He describes different contours and their meanings, but the word "meaning" stands apart from communicative function of intonation.is wide agreement among Russian linguists that on perception level intonation is a complex, a whole, formed by significant variations of pitch, loudness and tempo closely related. Some Russian linguists regard speech timbre as the fourth component of intonation. Neither its material form nor its linguistic function has been thoroughly described. Though speech timbre definitely conveys certain shades of attitudinal or emotional meaning there is no good reason to consider it alongside with the three prosodic components of intonation, i. e. pitch, loudness and tempo.. Sokolova and others write that the term prosody embraces the three prosodic components and substitutes the term intonation. It is widely used in linguistic literature, it causes no misunderstanding and, consequently, it is more adequate. They feel strongly that this term would be more suitable for their book too, but, unfortunately, it has not been accepted in the teaching process yet.foreign scholars (A. Gimson, R. Kingdon) restrict the formal definition of intonation to pitch movement alone, though occasionally allowing in variations of loudness as well. According to D. Crystal, the most important prosodic effects are those conveyed by the linguistic use of pitch movement, or melody. It is clearly not possible to restrict the term intonation by the pitch parameters only because generally all the three prosodic parameters function as a whole though in many cases the priority of the pitch parameter is quite evident.is no general agreement about either the number or the headings of the functions of intonation which can be illustrated by the difference in the approach to the subject by some prominent Russian phoneticians. T. M. Nikolayeva names three functions of intonation: delimitating, integrating and semantic. L. K. Tseplitis suggests the semantic, syntactic and stylistic functions the former being the primary and the two latter being the secondary functions. N. V. Cheremisina singles out the following main functions of intonation: communicative, distinctive (or phonological), delimitating, expressive, appellative, aesthetic, integrating. Other Russian and foreign phoneticians also display some difference in heading the linguistic functions of intonation.. Crystal distinguishes the following functions of intonation.functions most obvious role is to express attitudinal meaning - sarcasm, surprise, reserve, impatience, delight, shock, anger, interest, and thousands of other semantic nuances.function helps to identify grammatical structure in speech, performing a role similar to punctuation. Units such as clause and sentence often depend on intonation for their spoken identity, and several specific contrasts, such as question/statement, make systematic use of it.function helps draw attention to what meaning is given and what is new in an utterance. The word carrying the most prominent tone in a contour signals the part of an utterance that the speaker is treating as new information.function helps larger units of meaning than the sentence to contrast and cohere. In radio news-reading, paragraphs of information can be shaped through the use of pitch. In sports commentary, changes in prosody reflect the progress of the action.function helps us to organize speech into units that are easier to perceive and memorize. Most people would find a sequence of numbers, for example, difficult to recall. The task is made easier by using intonation to chunk the sequence into two units. Indexical function, along with other prosodic features, is an important marker of personal or social identity. Lawyers, preachers, newscasters, sports commentators, army sergeants, and several other occupations are readily identified through their distinctive prosody. [1,45]
1.2 Components of intonation and the structure of English intonation group
us consider the components of intonation.the pitch component we may consider the distinct variations in the direction of pitch, pitch level and pitch range.to R. Kingdon the most important nuclear tones in English are: Low Fall, High Fall, Low Rise, High Rise, and Fall-Rise. (see Appendix 1)meanings of the nuclear tones are difficult to specify in general terms. Roughly speaking the falling tone of any level and range expresses certainty, completeness, and independence. A rising tone on the contrary expresses uncertainty, incompleteness or dependence. A falling-rising tone may combine the falling tones meaning of assertion, certainty with the rising tones meaning of dependence, incompleteness. At the end of a phrase it often conveys a feeling of reservation; that is, it asserts something and at the same time suggests that there is something else to be said. At the beginning or in the middle of a phrase it is a more forceful alternative to the rising tone, expressing the assertion of one point, together with the implication that another point is to follow. The falling-rising tone, as its name suggests, consists of a fall in pitch followed by a rise. If the nucleus is the last syllable of the intonation group the fall and rise both take place on one syllable. In English there is often clear evidence of an intonation-group boundary, but no audible nuclear tone movement preceding. In such a circumstance two courses are open: either one may classify the phenomenon as a further kind of head or one may consider it to be the level nuclear tone. Low Level tone is very characteristic of reading poetry. Mid-Level tone is particularly common in spontaneous speech functionally replacing the rising tone. There are two more nuclear tones in English: Rise-Fall and Rise-Fall-Rise. But adding refinement to speech they are not absolutely essential tones for the foreign learner to acquire. Rise-Fall can always be replaced by High Fall and Rise-Fall-Rise by Fall-Rise without making nonsense of the utterance.to D. Crystal, there are nine ways of saying Yes as an answer to the question Will you marry me?
. Low fall. The most neutral tone; a detached, unemotional statement of fact.
. Full fall. Emotionally involved; the higher the onset of the tone, the more involved the speaker; choice of emotion (surprise, excitement, irritation) depends on the speakers facial expression.
. Mid fall. Routine, uncommitted comment; detached and unexcited.
. Low rise. Facial expression important; with a happy face, the tone is sympathetic and friendly; with a grim face, it is guarded and ominous.
. Full rise. Emotionally involved, often "disbelief or shock, the extent of the emotion depending on the width of the tone.
. High rise.mild query or puzzlement; often used in echoing what has just been said.
. Level. Bored, sarcastic, ironic.
. Fall-rise. A strongly emotional tone; a straight or negative face conveys uncertainty, doubt, or tentativeness; a positive face conveys encouragement or urgency.
. Rise-fall. Strong emotional involvement; depending on the face, the attitude might be delighted, challenging, or complacent.more pitch parameters are pitch ranges and pitch levels. Three pitch ranges are generally distinguished: normal, wide, and narrow. Pitch levels may be high, medium, and low.is used in a variety of ways. Gross differences of meaning (such as anger, menace, and excitement) can be conveyed by using an overall loudness level.tempo of speech is the third component of intonation. The term tempo implies the rate of the utterance and pausation. The rate of speech can be normal, slow and fast. The parts of the utterance which are particularly important sound slower. Unimportant parts are commonly pronounced at a greater speed than normal. [2,89]stretch of speech can be split into smaller portions, i. e. phonetic wholes, phrases, intonation groups by means of pauses. By pause here we mean a complete stop of phonation. We may distinguish the following three kinds of pauses:
. Short pauses which may be used to separate intonation groups within a phrase.
. Longer pauses which normally manifest the end of the phrase.
. Very long pauses, which are approximately twice as long as the first type, are used to separate phonetic wholes., there may be distinguished syntactic, emphatic and hesitation pauses.pauses separate phonopassages, phrases, and intonation groups. Emphatic pauses serve to make especially
