Every now and again I pick up a book and try to learn some new music. I am somewhat illiterate whan it comes to reading and theory. Just bought Bass Secrets (from Guitar magazine) and learned what a Pentatonic scale is. Can anyone tell me what the use of these are. I see it as just knocking 2 notes out of the major and minor scales - but don't see why. What's the purpose behind that? I have the feeling I might be missing something here. PS. If I keep going through this book I'm going to be asking a lot of seemingly dumb questions, but this is the best place I know to take it.
