have you just started playing guitar or are you moving to blues/jazz?
I dont knwo much baotu jazz but if you want to play some blue the best thign to do is spend some time learning the blues scales, then just improvise to easy 12 bar blues.
Listen to Hendrix's album called "jimi hendrix blues" (yes i know very original) but that should sort you out.
if at first your improvising doesnt sound too good dont worry. It takes time for ppl to get it together!
Happy blues! (contradiction!? :rolleyes: )
