Hirajoshi, or hira-choshi (choshi = tuning and hira
= even, level, tranquil, standard or regular) is the original solo koto
tuning which was developed by Yatsuhashi Kengyoo in the seventeenth
century and was adapted from Shamisen music. In the D-mode, hirajoshi
consists of the pentatonic scale: D, E-flat, G, A, B-flat.
Here are the pitches to which the strings of the koto are tuned
in hirajoshi when the tonic of the scale is D:
