I've bounced around from teacher to teacher the past few years learning "the basics". All of the teachers insisted that i start over again, which i willingly abided. But after a few weeks, or in some cases months, of the basics of scales i grew bored and stopped to learn by myself, and to save money because i felt like i wasnt learning anything new. When i write a song, I initially create (sometimes on a random occasion) a cool sounding riff. Half the time im stuck with this riff, because i cant find anything in my rarely creative mind to match up with this melody in my head. So my question is... Is there any books/videos/etc that i could buy that would help myself better understand the art of basic theory of music, and how chord (a) matches with chord (b), and so on. Sorry if i am doing a bad job of explaining what i want. To better refine my guitar teachers, they were all great teachers but i felt like i was being focused more around lead playing rather than rhythm. I also feel like i learn better by myself with books. Thanks guys, any help would be great!
