3. The phonological aspect of intonation.
Phonology has a special branch, intonology, whose domain is the larger units of connected speech: intonation groups, phrases and even phonetic passages or blocks of discourse.
The descriptions of intonation show that phonological facts of intonation system are much more open to question than in the field of segmental phonology. Descriptions differ according to the kind of meaning they regard intonation is carrying and also according to the significance they attach to different parts of the tone-unit. J.D. O'Connor and G.F. Arnold assert that a major function of intonation is to express the speaker's attitude to the situation he/she is placed in, and they attach these meanings not to pre-head, head and nucleus separately, but to each of ten 'tone-unit types' *as they combine with each of four sentence types, statement, question, command and exclamation.
M. Halliday supposes that English intonation contrasts are grammatical. He argues first that there is a neutral or unmarked tone choice and then explains all other choices as meaningful by contrast. Thus if one takes the statement I don't know the suggested intonational meanings are: Low Fall - neutral. Low Rise - non-committal, High Rise - contradictory, Fall-Rise - with reservation, Rise-Fall - with commitment. Unlike J.D. O'Connor and G.F. Arnold, M. Halliday attributes separate significance to the prе-nuclear choices, again taking one choice as neutral and the other(s) as meaningful by contrast.
D. Crystal presents an approach based on the view "that any explanation of intonational meaning cannot be arrived at by seeing the issues solely in either grammatical or attitudinal terms". He ignores the significance of pre-head and head choices and deals only with terminal tones.
It is still impossible to classify, in any practical analysis of intonation, all the fine shades of feeling and attitude which can be conveyed by slight changes in pitch, by lengthening or shortening tones, by increasing or decreasing the loudness of the voice, by changing its quality, and in various other ways. On the other hand it is quite possible to make a broad classification of intonation patterns which are so different in their nature that they materially: change the meaning of the utterance and to make different pitches and degrees of loudness in each of them. Such an analysis resembles the phonetic analysis of sounds of a language whereby phoneticians establish the number of significant sounds it uses.
The distinctive function of intonation is realized in the opposition of the same word sequences which differ in certain parameters of the intonation pattern. Intonation patterns make their distinctive contribution at intonation group, phrase and text levels. Thus in the phrases:
If Mary, comes let me  know at once (a few people are expected to come but it is Mary who interests the speaker)
If —>Mary comes let me  know at once (no one else but Mary is expected to come)
the intonation patterns of the first intonation groups are opposed. In the opposition I enjoyed it - I enjoyed it the pitch pattern operates over the whole phrase adding in the second phrase the notion that the speaker has reservations (implying a continuation something like 'but it could have been a lot better').
Any section of the intonation pattern, any of its three constituents can perform the distinctive function thus being phonological units. These units form a complex system of intonemes, tonemes, accentemes, chronemes, etc. These phonological units like phonemes consist of a number of variants. The terminal tonemes, for instance, consist of a number of allotones, which are mutually non-distinctive. The principal allotone is realized in the nucleus alone. The subsidiary allotones are realized not only in the nucleus, but also in the pre-head and in the tail, if there are any, cf.:
No. No, Tom. Oh, no, Mary.
The most powerful phonological unit is the terminal tone. The opposition of terminal tones distinguishes different types of sentence. The same sequence of words may be interpreted as a different syntactical type, i.e. a statement or a question, a question or an exclamation being pronounced with different terminal tones, e.g.:
