IN MOZART'S OPERA, THE MAGIC FLUTE, THE PRINCE TAMINO IS GIVEN A FLUTE. WHEN HE PLAYS IT, THE HEARTS OF HIS ENEMIES CHANGE. LATER HE KNOCKS ON THE DOOR OF THE TEMPLE OF WISDOM AND IS REFUSED ENTRY BECAUSE HE HAS VENGEANCE IN HIS HEART. HE PLAYS THE FLUTE AND IS ADMITTED ON HIS NEXT TRY. THE FIRST HEART TAMINO CHANGES BY PLAYING THE MAGIC FLUTE IS HIS OWN.
