Musical Mysteries is another good site from BBC Schools. It has a variety of games and activities to help learn music and sounds. It doesn’t actually have audio of how to say the simple words that describe the sounds, but there’s no shortage of sounds to describe.
I’ve placed it at the bottom of the Music and Art category of the my English Themes for Beginners and Early Intermediate page. While you’re there, you might want to check out quite a few other neat links to English language development activities related to the arts.
