I did a brief search here to see about any recommended sites on the subject but didn't come across much. In the beginning I absorbed some concepts of theory, but what I did understand was difficult to apply to actual spontaneous music or think about while actually playing, and have since pretty much ignored it to my own deficit. Of course now I realize the limits of "winging it" so to speak, and want to explore it further.

Obviously there's the tutorials and lessons here covering theory, not to mention just the pure discussion aspect of this part of the forum, but do ya'll have any other sites you'd like to recommend? This might be useful for not only myself, but any others looking for all the resources available.
