The shakuhachi is a Japanese end-blown flute traditionally made of bamboo. The standard length of a shakuhachi is about 54 cm, equivalent to the Japanese unit size of 一尺八寸 = 1-SHAKU-8-SUN. The fundamental sound of the standard shakuhachi is 'D' in Western notation. Other lengths are also used, the most popular being about 48 cm long, equivalent to the Japanese unit size of 一尺六寸= 1-SHAKU-6-SUN. The fundamental sound of this shakuhachi is 'E' in Western notation.

My 6-SUN shakuhachi was made by the Japanese maker SUIKOU (翠光), and I nicknamed it "Jiro"
