Quilisma (kwi-LEEZ-muh)

Virginia Tech has put together a Multimedia Music Dictionary. Besides a brief definition with any appropriate hyperlinked cross-references, each word has a recorded pronunciation, with quite zesty diction. There are musical examples, as long as you have the correct CD, and there are some quizzes (though I haven't found them yet). (via Elaine Fine as I get caught up on my blog reading)
