The shakuhachi
A bamboo tube with five holes and no mouthpiece — pitch is negotiated by breath and the angle of the head
Related
The shakuhachi makes the breath the instrument: no mouthpiece, no keys, five holes; the air jet splits on a sharp bamboo edge, and pitch is settled by breath angle, lip and head height.
The main line: a note has to be made to stand
A flute note is a point; a shakuhachi note is a process — breath first, a noisy attack, a swelling body, an ending pressed down or left open. It is not for tunes but for making one note stand up; a melody is a row of standings. "Ichion jōbutsu" (Buddhahood in one sound) is an ethic: one complete note is harder than many.
Form and sound: bamboo root, five holes, meri and kari
The 1.8-shaku tube is 54.5 cm and sounds D; another length transposes it. Madake is hollowed with its root, flaring into a bell; four front holes and one rear thumb hole, no duct. The bevelled utaguchi is the sounding edge.
Lowering the head pulls pitch down (meri); raising it lifts pitch (kari). A hole is a band, not a point; deeper meri is darker and breathier. The range fence gives C4–G6, common D4–G5.
Institution and relatives: komusō, two schools, three flutes
The "Zen" label comes from the Fuke-shū and its komusō, who played honkyoku as practice, called it suizen, and held "one sound, Buddhahood" as an ideal. The Edo shogunate granted them passage privileges; in 1871 the Meiji government abolished the sect. Tracing it to the Tang monk Puhua is traditional; the spy image is legend, not fact. Modern schools are Kinko-ryū (eighteenth century) and Tozan-ryū (1896); Takemitsu's November Steps (1967) brought the instrument into the orchestra.
The ney is also an end-blown edge flute without a duct, but a reed tube with six holes plus a thumb hole. The Western flute is transverse and keyed; the xiao is an end-blown bamboo flute without the root bell.
Three things to take away
1. No mouthpiece: lips, chin and head angle are the instrument. 2. Meri and kari: pitch is a movement, not a key. 3. One sound, Buddhahood: one complete note is harder than a full phrase.

A 1.8-shaku tube sounds D; another length transposes the band. Meri lowers and kari raises pitch within one fingering. The figure gives C4–G6, common D4–G5: C4 needs a deep meri, G6 sits at the edge of the second register. Pitches are sounding.
