I've some to the realization that I have no real sense of melody (i.e., writing melodies is extremely difficult) and my improv skills are sorely lacking. I think I've become the weak link in my band, and it's not a good place to be. I've tried learning my scales, and I've tried to learn to read music, but I think I have ADD (or I'm just extremely lazy... yeah, that's probably it) since I lose interest after about a day. Are there any good books/ videos that address either melody or improv? I've been playing for about 6-7 years, so I can get around a bass pretty well, just can't play as well as I should. Any and all help is greatly appreciated.
