Right, so lately I've been interesting myself in harmony and composition and I was thinking I might get a big book to help me a bit. Now I've searched around a bit on the forum and I've found this:



Any more suggestions? I'm looking for a dense book that I can work with slowly and over a large amount of time. Hopefully it should serve me as a reference as long as I have it. I want to have my hand at more serious composition in the future (as in not only guitar music but maybe chamber music and similar stuff) and I feel that I definitely need more theoretical knowledge to do this.

http://www.amazon.com/Harmony-Fifth-Walter-Piston/dp/0393954803 is the one I'd recommend.

I believe the edition I have isn't the one linked which has been revised; but provided they haven't re-written it completely then I don't know of any better text on harmony. It is very dense and will take you a long time to understand and digest it all; given that, some basic knowledge is pre-requisite. I wouldn't recommend it if you're not au fait with basic theory and harmonic conventions.
The Mel Bay book is certainly dense, but if that's what you want, then sure. Other than being a bit to dense, it's actually a nice book.

Anyone familiar with this one? Any more suggestions? Perhaps from those of you have completed or are in the process of completing uni courses?
