Dancers and directors correlate with music differently.
The maestro and the dancer both will gyrate with the beat
Yet there’s a deeper difference than moving hands or feet.
Both movements correlate quite well to what the band doth play
But dancers are the caused, it seems, and can’t the music sway.
The maestro is the cause instead, the music tracks the arm,
Though causal power’s weak enough there’s little scope for harm.
The dancing and directing, they are of a single breed:
The difference is in which doth lead and which must leaders heed.
