The Dancer abilities are Witch Hunt (reduces enemy MP), Wiznaibus (reduces enemy HP), Slow Dance (lowers enemy speed), Polka Polka (lowers enemy PA), Disillusion (lowers enemy MA), Nameless Dance (status effects), and Last Dance (lowers enemy CT to 0).
The Bard abilities are Angel Song (restores ally MP), Life Song (restores ally HP), Cheer Song (raises ally speed), Battle Song (raises ally PA), Magic Song (raises ally MA), Nameless Song (can give beneficial status effects), and Last Song (fills ally CT to 100).
Clearly, then, Witch Hunt corresponds to Angel Song, Wiznaibus to Life Song, Slow Dance to Cheer Song, Polka Polka to Battle Song, Disillusion to Magic Song, Nameless Dance to Nameless Song, and Last Dance to Last Song.
