re Tanaka and the Kleisma

Tanaka defined the Kleisma (Greek for lid or lock) as 6 minor thirds
(6/5) down and a further 4/3 down, the interval between c# and fb (with
a bar over the f in his notation), the ratio 15625/15552 or 8.107+
cents. See Tanaka,Shohe'. 1890. "Studien im Gebiet der reinen
Stimmung." pp. 1-90, _in_ Vierteljahrsschrift fuer Musikwissenschaft,
