Ok, I've been invited to play in a school band consists of this: 5 singers (they harmonise together really nicely actually, and they're all girls, heck yeah!) A pianist A bassist And then there's me, another bassist. The first song we're playing is black velvet in E minor. I also play slide guitar on my cigar box guitar, so I could get the fills on that, but if I were to play bass, what would I play? The bassist would be playing the main riff, so I'm stumped as to what to play.
