Chant and music
Noh theatre is accompanied by a chorus and a hayashi ensemble (Noh-bayashi 能囃子). Noh is a chanted drama, and a few commentators have dubbed it “Japanese opera“. However, the singing in Noh involves a limited tonal range, with lengthy, repetitive passages in a narrow dynamic range. Clearly, melody is not at the center of Noh singing. Still, texts are poetic, relying heavily on the Japanese seven-five rhythm common to nearly all forms of Japanese poetry, with an economy of expression, and an abundance of allusion. The singing parts of Noh are called “Utai” and the speaking parts “Kataru”.
The chant is not always performed “in character”; that is, sometimes the actor will speak lines or describe events from the perspective of another character or even a disinterested narrator. Far from breaking the rhythm of the performance, this is actually in keeping with the other-worldly feel of many Noh plays, especially those characterized as mugen.
Noh hayashi ensemble consists of four musicians, also known as the “hayashi-kata”. There are three drummers, which play the shime-daiko, ōtsuzumi (hip drum), and kotsuzumi (shoulder drum) respectively, and a shinobue flautist.
