*Key is the pitch sounded with all the holes closed.
Finger Hole numbers are counted starting from the bottom of the flute.
Japanese Name of Open Hole Notes: RO, TSU, RE, CHI, RI, RO' (Second Octave)
Open-Hole Pitches listed under each finger hole number assumes that the holes below it are opened as well.
Alternate Pitches are produced by cross-fingering and changing the angle at which the shakuhachi is blown (Meri/Kari). See Fingering Chart.
The fingering charts, while based on the 1.8', shows that any shakuhachi can be played a semitone lower than the nominal key by blowing and holding the flute in the various meri positions: Ro Meri, Ro Chu Meri ["Half Meri"], or Ro Dai Meri (or O Meri) ["Big or Deep Meri"].
Each column represents an interval of one semitone.
Based on the equal temperament system of tuning, some notes designated as sharp (#) can alternately be referred to by their flatted equivalents. Hence, for example G# is the same frequency as A-flat. For the sake of convention, I have referred to notes using the flat accidental rather than the flatted designation. In fact, they are the same musical note.
In its traditional music, the shakuhachi has a range of approximately 2 1/2 octaves. Some notes above this can be produced
Length measured in centimeters is approximate and can vary slightly with each flute.
