I have been playing bass since 1988 or so, but like many players I am mostly self taught. I have taken lessons here and there. As I get older, music theory and the mechanics of music are becoming more important... that being said there are HUGE gaps in my knowledge of music. My question is... I have been playing and practicing scales since '88 and I was wonder how musicians (esp. you blues and jazz guys) use them when you are improvising with a band. In the past, someone will say "Hey this song is in A" and I would listen and choose appropriate notes from an "A" scale. Sometimes it takes me a while to get a "feel" for it... I am hoping to increase my understanding to cut down the "feel for it" time. Suggestions? Links? Reading material?
