A bandmate has noticed that I tend to play slightly ahead of the beat when playing a walking bass line. A couple of indications suggest that I'm not rushing, per se: 1. Bands that I play with don't speed up 2. When I play by myself, I can hold myself pretty close to a metronome marking with the metronome turned off So far this bandmate is the only person who has ever complained, but I'd like to know if there's an exercise that would help me get myself on top of the beat if I wanted to play that way. Thoughts?
