Earworm is a worm that lets kids train their ears. It sings a melody and your child sings it back by ear. You don't need to know notes or intervals, but there is always a chance that you will learn it while playing. Earworm has six friends which sing with different voices. Can you sing like an elephant? Or croak like a frog? Sing the 16 simple melodies and check if you did it correctly.
