I'll be singing tonight, at choir practice. Then again Sunday morning.
I'm the only bass, which is ironic, because I'm actually a tenor with a wide range. I can't hit the really low notes (A an octave below middle C is about it if there's to be any volume), but it's better than the other two tenors can do, so I'm bass by default (on a good day, I can sing with the altos, too).
But when we did the Hallelujah chorus for Easter, I sang tenor because the other two guys can't hit the really high notes anymore... so they sang bass. Handel was a sadist, anyway.
