In Daegu dialect one can find five types of tone. Two of them-high and non-high-are assigned to syllables with a short vowel ; the other three-rising, falling and low-level-to those with a long vowel.
The investigation into forms consisting of only short syllables shows that the high tone manifests itself in connection either with a single syllable (type b) or with a sequence of more than one (type a) within each relevant syllable chain. By assuming a unit called “mora ” which has a length equivalent to a syllable with a short vowel, accent patterns of these forms can be described as arrangements of morae with high and non-high tones. Using this analysis, accent patterns are distinguished by, (1) the position of the “kernel mora” that is the last mora with a high tone within each relevant word or phrase, (2) the tone of the mora immediately preceding the “ kernel ”(distinction between types a and b), and (3) the number of constituent morae.
The three types of tone in syllables with a long vowel are thus analyzed as different combinations of high and non-high morae in respect totheir length and direction of tone-movement: the rising tone as a sequence of a non-high mora followed by a high mora, the falling tone as a sequence of a high mora followed by a non-high, and the low-level as a sequence of two non-high morae.
Analyzing in this way, the system of accent patterns in Daegu dialect can be described in terms of tone-sequences composed of two distinctive heights within each word or phrase without regard to vowel quantity.
