A recorder shouldn't be hard to model or animate the finger positions for. (The hands don't move, just the fingers, so there is no stretching involved.) The same fingering is used for most end-blown flutes and bagpipe chanters and such, depending upon key and range. Being single notes rather than chords also means that even amateur musicians can stand a decent chance of making music (it helps that it is hard to get bad sounds out of a recorder). This would be useful for Renaissance angels, pied pipers, shepherds wooing lassies.... :) Carolly
