Re: Morning versus Evening Ragas

Dear Doug & List,

Enculturated listeners as well as experts certainly can do this. The association between Ragas and times of day is characteristic of North Indian musical practice, I believe. You can/should look up "Raga" and "India" in the Grove Dictionary of Music (Oxford Online). Another good/related source is:

Widdess, Richard (1995) The Ragas of Early Indian Music. Clarendon Press (OUP).

I suspect your interests might be along the lines of "what in the acoustical signal distinguishes one raga from another" and this is tricky to tease out. To give a western musical analogy, the difference between a Baroque minuet and a gigue rests on a few characteristic features (mostly in terms of characteristic rhythmic figures and tempo), but also depends on lots of features in common with Baroque music more generally (e.g., timbres, intonation systems, basslines, etc.).

All best,
Justin London

I'll get an answer or two.

I'm curious about morning versus evening ragas.  Can musical experts
tell them apart?  What are the qualities that define a morning versus
evening raga?
Is it something that would show up via an acoustical analysis of the
audio drawn from lots of morning and evening ragas?

Citations would be great. Or just some observations.

Thanks in advance,
