What did you find in your research so far?[/quote]
The best book so far is one which comprises many writings/essays from across the musical spectrum, it’s called “Audio Culture, readings in Modern Music”. The topics range from Music Concrete to Dub, chance composition, all sorts of stuff.
Another I found interesting was called “Groove, a phenomenology of rhythmic nuance”. The author sets out to clarify what indeed groove is and how we perceive it.
I’m giving “How Music Works” by David Byrne a read, but in comparison it seems to be more of his artistic opinion (from what I’ve read so far!)
