I need some guidance about how to become a useful bass player that people want to play with. I have a classical music background (trombone, recorder, lots of choir singing), so I read well and have some idea how to practice to develop technical proficiency, particularly if the music is written! I've been practicing steadily for about a year and a half. I'm doing lots of scales and (slowly) working through the Standin' in the Shadow of Motown Jamerson transcriptions and playing along with lots of Arethra Franklin and Duck Dunne tunes. From reading posts here, though, it seems what matters most to being a valuable bass player is rock-solid rythem and being able to develop a bass line on the fly, more than being able to throw off fast sixteenth notes. I don't have a good fix on learning these skills, and I don't have the chance to play regularly with others, and have no opportunities to play the soul I am learning. What should be my practice priorities to become a useful bass player? I'm starting to practice with a metronome, but I'd appreciate any other feedback.
