Here’s a musical game to play to ‘Crocodile, Crocodile’ where you get to sing the song, and play and name some random notes at the end.
Some ideas and variations to play are listed at the end of the song.
Repeat it over and over as an earworm to play and name the notes you are working on. The piece is in C major, so any notes in that scale are okay to play and will work well.
For violin students: the teacher can play the song on the piano or the violin, and the student sings the song. Then the student can play and name the notes at the end, or choose which variation would work for you.
You could even use call and response with the notes of your choice at the end – the teacher plays and names a note, then the student plays and names it.
