Hello, my name is Felix, and I'm a self-taught "guitarist". I'm not sure for how long I've been playing, or learning to play, but I'm sure it's not nearly enough

. Anyway, you could call me a strummer - I know chords, barre chords, and I'm messing with tabs. The thing is I would like to learn more about music, and how it's formed, and some theory to make me understand what's going on. Since I don't have a teacher, I was never exactly sure what to practice... I tried a few times to get a schedule for practice, and follow some lessons online that treat you as you have your own teacher - tell you what to practice, how long... But, since I was interested in other stuff, I did other stuff. I can say I somehow mastered chords with time, and some tabs, I'm pretty good with barre chords now, too. I think it's time to learn some serious music theory to begin understanding, but I have a problem: where to start? Whenever I look at some site with lessons of that kind, I kind of get confused and go away, because it doesn't seem to make sense to me, or I get lost. Luckily, I've found this site recently, and I read about
PlaneTalk. At the beginning, I thought it was just another magic book like that in a row, or only for more experienced players because it also mentioned scales etc. Then, after reading more, and finding out that it's based on basic chords, it looked more interesting. After reading somebody's review which claims it IS for beginners, I was encouraged. Because, I guess I know my technique, I know my chords, but I never went deep into scales and modes because they always seemed unclear to me. Anyway, I know PlaneTalk is all about chords, but does it teach you what you need to know before doing this trick, like, if it requires you to know something about major scale, it tells you about it? Another thing I'd like to know - if it's based on chords, do you need to know the chord to use it, or it shows you how to "build" the chord?
Sorry for a little long post, but I had to ask
