All of the recent threads on books has got me wondering. Are music books a part of your regular learning regime? In the 90s I bought tons of music books (well, pounds anyway). Books with standard notation, tab, books with CDs. Some helped. Most (to be honest) didn't, but that didn't stop the search. I was always hoping something would help me unlock the next level. Fast forward to now...virtually all of my learning comes from videos. YouTube, Truefire. Despite having less time to practice, I am advancing faster than I ever did back then, and I have not bought an instructional book in ages. Am I missing out? Do you still regularly work with books? Are there favourites that made a big impact on how you play or how you understand music? Recent publications that you think are game changers? Old faves that you still go back to?
