The eight-beat Yatsubyōshi rhythm structure is the most basic in Noh. The vocals that match the rhythm, known as kyōshiai, place great emphasis on which syllable corresponds to which beat. In principle, every phrase is sung in eight beats. Maigoto, or dance pieces accompanied only by music – such as naka-no-mai, otoko-mai and kami-mai – are also performed in eight-beat, showing the rhythm’s close links to Noh performance.
