Gamelan is an Indonesian musical ensemble comprised primarily of large metal percussion instruments. Today there are many gamelan programs in the U.S., including an excellent one at the University of Michigan in which I have played, off and on, for five years.
An Introduction to Javanese Gamelan
I put this cartoon introduction to the gamelan together for the University of Michigan ensemble's 2013 performance. If you would like to use it for educational purposes or for your own gamelan ensemble's performances, feel free to download this file. It's designed to be printed double-sided and folded into a simple four-page booklet.
Javanese gamelan has a reputation for being very soothing music, but that doesn't mean playing in one isn't a lot of fun.
