'Kusemai' ('曲舞'or'久世舞')was a popular
Japanese form of song and dance with a strong irregular beat - emphasis is placed on the beat at the expense of the melody. This type of music particularly flourished around
Kyoto and
Nara, in the fourteenth and fifteenth centuries. The name can be roughly translated as "peculiar/unconventional dance." Although dance was originally involved with the performance, it was of minor importance, and probably involved the performer simply stamping the beat.The playwright
Kanami incorporated it as part of the formation of his famous
Noh theatre style.
