This is a Japanese Traditional Hand Made Shakuhachi in the Key of A , from the Tozan school.

The Shakuhachi is a Japanese longitudinal, end-blown flute that is made of bamboo. The bamboo end-blown flute now known as the shakuhachi was developed in Japan in the 16th century and is called the fuke shakuhachi 普化尺八 Shakuhachi are usually made from the root end of madake (Phyllostachys bambusoides) bamboo culm and are extremely versatile instruments. Professional players can produce virtually any pitch they wish from the instrument, and play a wide repertoire of original Zen music, ensemble music with koto, biwa, and shamisen, folk music, jazz, and other modern pieces. Much of the shakuhachi's subtlety (and player's skill) lies in its rich tone colouring, and the ability for its variation. Different fingerings, embouchures and amounts of meri/kari can produce notes of the same pitch, but with subtle or dramatic differences in the tone colouring. Holes can be covered partially and pitch varied subtly or substantially by changing the blowing angle. The Honkyoku pieces rely heavily on this aspect of the instrument to enhance their subtlety and depth. Unlike a recorder, where the player blows into a duct—a narrow airway over a block which is called a "fipple"—and thus has limited pitch control, the shakuhachi player blows as one would blow across the top of an empty bottle (though the shakuhachi has a sharp edge to blow against called utaguchi) and therefore has substantial pitch control. The term utaguchi 歌口 literally translates as "to the mouth that sings", referring to the upper and main hole of the flute where the mouthpiece or blowing edge is created by a natural diagonal cut in the bamboo
