Music Theory throughout the ages?

[Death by Hamste]

Hello, so what i'm looking for, if anybody can help, is a book that analyses music from different cultures or ages. For instance, what makes Medieval music sound like medieval music? From a theory point of view, ie the different uses of Harmony, or chord progressions etc.

I'm basically just looking for anything that relates to the above, ie i don't mind what kinds of music or period or culture it's looking at, be it English folk throughout the ages, or indian classical music.

Cheers,
Jack.

A fantastic site for medieval theory is this one on Early Music:
http://www.medieval.org/emfaq/harmony/

And this one has a good overview of theoretical development starting from Pythagoras and the Ancient Greeks (hey, there's a good name for a band... ;) ):

As you asked, here's a couple I like on Indian classical music (North Indian, at least):

BBC Radio-4 has a new 6 part series called The Making of Music, which traces 1000 years in the history of western music … the series started yesterday (Mon 4th June) but it goes on for the next six weeks. Here’s a link to the BBC website describing the program …may be interesting to you http://www.bbc.co.uk/radio4/makingofmusic/ (http://www.bbc.co.uk/radio4/makingofmusic/) .
