Basic Types of Tone-Sequences in English
Explanation
When analysed for the nuclear tones in each of the component-parts, combined tunes may be described as sequences of tones, or tone-sequences.
The most general observation concerning this subject is that tone-sequences in English display relatively free combinability of nuclear tones. Even the simplest tone-sequences, i.e. di-s eque n c es, demonstrate a fairly wide range of possibilities.

Obviously, in longer sequences the number of possible combinations of nuclear tones is considerably increased.
However free the use of nuclear tones in the adjacent intonation-groups may seem, there are certain underlying tendencies in their choice. First of all, there is some evidence that the choice of a nuclear tone in an intonation-group is to a considerable degree determined by the immediately preceding nuclear tone. In other words, there is a high probability of tonal reduplication, which means that if there is a fall (or, let us say, a rise or a fall-rise) in the preceding group, there is a tendency to use the same or a similar kind of nuclear tone in the following one.
The purpose of such a repetition of tones in adjacent groups seems to consist in keeping the same attitude throughout an utterance as a means of linking its parts more closely together. The use of varying nuclear tones in adjacent groups, on the other hand, serves to indicate a change in the speaker's attitude.
In di-sequences, or in the last pair of groups in a longer sequence, the tendency towards similarity of nuclear tones is much weaker. The difference between the nuclear tones of the final and non-final intonation-groups and the use of different types of nuclear tones in final and non-final intonation-groups is much more typical which can be explained by their specific roles in the organization of an utterance - the nuclear tone of the final group marks the communicative type of an utterance, while the choice of the nuclear tone in the non-final group is determined by the degree of the semantic independence and completeness of the latter.
