Hocchiku flute calculator: the shakuhachi flute is a Japanese end-blown flute which is held vertically like a recorder, instead of transversely like the Western transverse flute. It is traditionally made of bamboo, but versions now exist in wood and plastic. It was used by the monks of the Fuke sect of Zen Buddhism in the practice of suizen (blowing meditation).
