That was a very informative, well researched and neat presentation.
I've given it a quick glance, it needs some discussion to understand
it completely, particularly in the first section. (ex. Slide 5:
Symphony - Soprano, alto, tenor, bass?? 4 part writing is a basic
structure in western music, of course it has some links with symphony
too.. I couldn't guess what you are trying to point out here.
Similarly, Stereophonic? Antiphonic?)
Anyways, the main content is in section 2 and 3. I'll go thru them
once again thoroughly before coming here for a discussion. I liked the
fact that you've researched well about Tamil Isai and vedic music in
this presentation. I also liked the way formation of notes (5th cycle
& 4th cycle, starting from undivided string) is presented.
I couldn't agree completely to the chart presented in slide 18,
comparing western and carnatic frequencies. Westerners experimented a
lot with different tuning systems too. For instance _Just intonation_
is quite similar to our tuning system (

Just_intonation).
Good work. It deserves some discussion here.
Thanks for sharing.
