Three or five?

A leap of three is Saints. A leap of five is Twinkle. Hear the tune, know the leap.

Three: do to mi. Oh when the saints

Five: do to so. Twinkle, twinkle

Four, from before. Amazing Grace, in between

What you sing

  1. Each clip starts with the key's chord. Which leap is it?
  2. From new notes: the guide gives the first note, and you sing the named leap from it.
