Walter Piston, _Harmony_

[jim]

An relatively expensive textbook, this is one of the standard sources for learning Harmony. If you can't snag a copy, consider checking one out from a library and visiting a photocopier. The first few chapters are highly readable, and extremely useful if you've never learned this stuff before.
