Ritsu (εΎ‹), the anhemitonic pentatonic of Japanese court music and Buddhist
chant: offsets {0,2,5,7,9}.
Two ritsu tetrachords a fourth apart: the middle note sits a whole tone above
the lower nuclear tone. The result is the same five pitch classes as the
major pentatonic a fourth above, which is why the mask alone cannot say which
tradition is meant.
