| Nuclear stress
From a functional point of view nuclear stress is the only obligatory stress in an intonation-group and signals the central point of information. The specific structural features of nuclear stress are connected with its location in an intonation-group: 1) it is normally associated with final pitch change, which means that there are no other significant (i.e. perceptible) pitch changes following it; 2) it occupies a relatively fixed position in an intonation-group: in the absence of any disturbing contextual factors it falls on the last content word. 70 Nuclear tone The kinetic tone carried by the most important word (which is generally the last notional word) is called the nuclear tone. Nuclear tone-shift When it is desired to reinforce the semantic weight of the nuclear word it can be done by using the so-called nuclear tone-shift, which means displacing the nuclear tone from its normal position – on the last notional word in an utterance – to a word at the beginning or in the middle of it. The effect of a departure from final position is that of special semantic prominence or contrast. The effect of a contrastive tone-shift is always greater when the nuclear stress is given to a function word. O One-peak (compact) head The first semantic tem of an utterance bears a full stress, i.e. becomes the onset of the head, and all the other content or potentially prominent form words are given partial stresses to show their smaller semantic importance, or they may be left altogether unstressed. The whole head in this case produces the impression of a closely-knit semantic unit with one peak of prominence in the initial position – one-peak, or compact, head. жүктеу/скачать 0,6 Mb.
