This gives yet another version of srutis, which isn't in the Scala
directory but is close to indian2. It's by P. Sambamoorthy, who back
in 1954, it seems, was head of the department of Indian music at the
university of Madras.

Once again, the scale follows the general sruti principles; it
contains Sa-magra, and takes for srutis for 9/8, 3 for 10/9, and 2 for
16/15. I give it below, but there is an alternative which has 729/512
in place of
64/45, which is a schisma higher.

It's interesting that this thread is headed in the
same direction as what i just posted in response to
Neil regarding pythagorean schismic near-equivalents
of 5-limit JI ratios. Lentz ignores the skhisma
difference is changing his discussion of srutis away
from really large pythagorean ratios to their nearly
equivalent but much simpler 5-limit cousins.
