| Berklee College of Music here in Boston has some easy-to-read, well-written books on harmony that they use as texts for their classes. I'd see if you can't order some of them online.
In particular, you could check Boston Craigslist for used texts from students from the previous semester, though shipping overseas might negate the benefit of a cheaper book.
EDIT: I'd also recommend you track down a "Fake Book" (sometimes they're also called "Real Book"), which is a book of photocopied jazz charts that you can study and play to, which will help you train your ear as well as help you begin to notice harmonic patterns (ii V I turnarounds, for example). |
