I'm sure there's been a thread like this, but I can't seem to find one.
As some of you know, I have been playing improv piano for about five years and have done a little composing on the side. However, I recently decided to seriously study composition on my own (i.e. without taking a course). What books should I use? I am well-versed in basic theory (so I'm fine with technical texts), but know little about the craft of composition.
Any help would be much appreciated.
