演歌・メロディーパターンの類似関係(<一般演題>境界領域)

抄録

A characteristics common to melody lines in ENKA (a traditional-style in Japanese popular song) is described in this paper. Feature patterns extracted from the power spectrum of melody lines in Japanese popular songs are analyzed by using fuzzy clustering. From the analysis, there exists a distinctive cluster where ENKA melodies are assembled. A rough style of the melody lines in ENKA is reasoned by analogy from the feature pattern common to the cluster. A melodic style common to ENKA is cleared when we take a view of the melody lines from long time axis in comparison with a melody length. From analyzing the feature pattern, it is recognized that the rough straight-line representing a melodic line is modulated by ups and downs fluctuations and the strong correlation between a note and front note can be expected in the melodic progression in ENKA.
