Create your own Musical Instruments
Put rice in a tiffin box, secure the lid, and shake it. And you have a shaker!
Or take two spoons, have them face each other back to back, secure them with rubber bands at their necks, and hit them against your palm. Using these instruments, create a basic 4 x 4 beat, write down a few lines of lyrics, and sing it.
What might be more fun for the children would be to rap the lines.
