When auditioning singers with only guitar and bass, playing cover tunes, is it important to play a bass part close to what's on the recording? I don't want to throw off the singer or anything, but I don't really have enough time to learn all the recorded bass parts of all the tunes for a bunch of upcoming auditions. The guitarist already knows most of these tunes, so he's okay, but is it bad for me to just use chord charts for the songs I don't get to? I do try to make sure I know riffs and parts that I think are really important for the song, but for the most part, I guess I do it for the sake of the guitarist. What would an auditioning singer expect from the bass player?
