Sounds awesome! I'll be recording a Tibetan singing bowl utau soon, and once I build my chops back up a baritone/euphonium one too. I think this is an awesome idea!
I've never heard of a Tibetan singing bowl. That's going to be really cool! My brother also plays the baritone, maybe I can get him to record a baritone UTAU too and they can have a duet XD
