Yeah, lilypond is awesome. I actually used it to typeset a piece of music that got published as an arrangement for handbells! http://www.beckenhorstpress.com/title.asp?id=HB317

Bonus points if you can name the actual piece (the publisher didn't want me to use the actual title for the published arrangement).
