On the Subject of Festive Piano Keys

Let’s all gather round for a family sing-a-long!

  • A festive piano keys module presents 3 musical symbols and a 12-note keyboard.
  • Each rule needs one or more symbol(s), plus optional bomb requirements.
  • Scan rules top-to-bottom; the first matching rule gives the note sequence.
  • A strike requires re-entry of the full sequence.
