Kraig:

Although Paul Erlich probably does use the term "ancient Indian music" a bit
loosely, you should keep in mind that the drone appears to have been
introduced fairly recently -- earliest in the 16th century -- so there is an
important change in the character of the music at that time, although the
theoretical tradition appears so seemless.

I cannot comment about Hindustani music, but I have measured many a
(Karnatic) vina fret, and they tend to be tuned rather than tempered, a
finding in contradiction to Erlich's. Where one of the 12 frets has to cover
more than one distinct pitch, one of the two is chosen, and the other is
reached by bending.
