I'm relearning guitar after several years -- well, several decades -- away. I'm actually finding that not only is it coming back to me easily, but I'm learning more than I ever knew before due to all the amazing resources available on the Internet.
Which gives rise to my question. I'm relearning the rock and roll that I played as a kid, but at the same time I'm studying jazz chords, learning pentatonic scales, practicing blues solo techniques, and on and on. I'm wondering whether it's wise to do these things all at once, or if it's better to spend a few weeks concentrating in one area before moving to the next. So far I feel like I'm progressing in each line of study, but would I learn more efficiently if I specialized?
