I would love to get into jazz music, though as a guitarist it's a big step for me. Before now I've played mainly blues, blues rock, that sort of thing, and picked up a fair few (probably bad) habits that don't bode well with playing jazz music.
Some pieces are within my reach, though others, particularly solo pieces with frequent chord changes, are most challenging as I've gotten so used to using only a certain number of shapes which aren't really applicable now. Having said that, I will struggle on and try and widen my musical vocabulary.
