@CinnamonGirlE You can just play around with one of these. All the notes are harminious, so nothing sounds bad together.
But I can tell you how to play "Mary Had a Little Lamb". 3-2-1-2 333 222 355. 3-2-1-2 333 32 32 31. Works on these drums, pianos if you can find middle C and count from there, and telephones.

I may have to get one and give it a try. It looks like loads of fun. And I think it would be therapeutic.
