This study identifies distinguishing features and variability of intonation patterns in Korean phonological phrases. Syllable count and segmental content, which are phonological conditions, of the intonation of phonological phrases were examined. Based on the four syllables, the intonation of a phonological phrase can be set to LHLH as the basic form, and syllable count acts as a condition for making a variation. The "3 syllables or less condition" changes the intonation from a curved line to a straight line. Variation occurs in pitch bandwidth and fluctuation according to segmental content. The first segment affects the phonological phrase formation bandwidth, and the following segment affects the pitch fluctuation. If the first segment has [+aspirate], [+tense], [+continuant], the intonation is formed in the high band, otherwise, it is formed in the low band. If the second or after segment in the intonation realized in the high band has [-aspirate], [-tense], [-continuant], the pitch is lowered to the lowest level of the low bandwidth. In the intonation realized in the low band, [+aspirate], [+tense], [+continuant] is blocked by the second descent of LHLH.
