I've played music on a trumpet, a treble clef baritone, shotgun barrels (not attached to a shotgun at the time), a garden hose, a bugle, a hunting horn, a sea shell, and a bunch of other things. But never a moose horn. The ones I've seen didn't have a place to blow into and/or they were still part of the moose. And they seem kinda flat, like you wouldn't get much tone from them.

Do moose blow their own horns?
