THE origins of traditional Japanese music reach back more than a thousand years. Included are classical or refined music, chamber music, theater, folk and festival music, as well as a host of vocal forms. This treasury of music was passed on from generation to generation without the help of musical scores. Between the third and fifth centuries C.E., Buddhist missionary priests came to Japan to spread their views. The chants and background music associated with their religion gradually merged with the Shinto traditional music, forming a basis for nearly all native Japanese music. By the seventh century this music of Japan developed into what became known as Gagaku, the classical (literally, “elegant”) music. From Gagaku, which became the music of the imperial court, the secular use of instrumental music grew, as did theatrical music. Meanwhile, folk and festival music appeared, with its loud drumming and lively rhythm, contrasting sharply with the quiet music of Gagaku. This instrument has five finger holes, and a mouthpiece at the upper end. The player holds the shakuhachi vertically. By skillfully adjusting his lips to the mouthpiece at varying angles and moving his neck into different positions as he covers the holes with his fingers, the instrumentalist is able to produce three octaves of tones.
