抄録
The shõ 笙 serves as the standard of pitch ih the gagaku 雅楽* Japanese classical court-music, and produces 11 sorts of peculiar accord called aitake fit. The writer desired and endeavoured to know in detail of the tuning of the sho, and, if passible, to give a reasonable explanation to the aitake. The result is satisfactory, and a very simple method is proposed to express numerically the degree of concordance of not only these 11 aitakes but also of almost any accord.
