I have been playing for about 3 years now, but gravitate toward single note lead lines, thus my chording ability is seriously lacking. My instructor refers to me as 'BB' as in King, as he exemplified that type of style (not that I'm anywhere near his ballpark!). Anyway, I want to concentrate on further developing my chording technique with work on progressions, etc. Anyone know of a good book in that area that is fun to use and covers both the blues and jazz spectrums? Thanks!
