Well, I sorta know how to read music (though most stuff I play is from tabs) but what I really want to be able to do is play licks and solos in any key I'm in. I've been digging into pentatonics and major scale patterns and what not for some time but it seems that there's gotta be some sort of systematic method in acheiving all these. But then again, I could be wrong and maybe it's because i'm not confident enough just because I haven't received any formal training in that area. By the way, is it really worth all that money to receive lessons? any testimonials?
