Shakuhachi
The shakuhachi (尺八、しゃくはち, pronounced [ɕakɯhatɕi]) is a Japanese end-blown flute.
It was originally introduced from China into Japan in the 8th century and underwent a resurgence in the early Edo Period. The shakuhachi is traditionally made of bamboo, but versions now exist in ABS and hardwoods. It was used by the monks of the Fuke school of Zen Buddhism in the practice of suizen (吹禅, blowing meditation).
The instrument is tuned to the minor pentatonic scale.
Overview
The name shakuhachi means "1.8 shaku", referring to its size. It is a compound of two words:
shaku (尺) is an archaic unit of length equal to 30.3 centimeters (0.994 English foot) and subdivided in ten subunits.
hachi (八) means "eight", here eight sun, or tenths of a shaku.
Thus, "shaku-hachi" means "one shaku eight sun" (almost 55 centimeters), the standard length of a shakuhachi. Other shakuhachi vary in length from about 1.3 shaku up to 3.3 shaku. Although the sizes differ, all are still referred to generically as "shakuhachi".
