Music games

Sing or Dare: "Sing" cards like "sing [the song] while marching the beat" or "sing the song, but buzz all the words 'the'."  "Dare" cards like "Name everyone in the room" or "Hug the teacher."  (I think I might change the dares to musical things like "sightread a simple song" or "play the melody on the xylophone.")
