I was at a musical event a while back and as I saw the brass instruments a question popped my mind, could an animal come with an instrument built in? It seems far fetched but evolution has given us some odd creatures, If this creature could exist what would be its evolutionary be like, and If it couldn't evolve why not? what would the difficulties and problems be?
By musical instrument I mean a wind instrument, such as a trumpet or trombone that creates their sounds or similar.
I do not mind broad answers, like Bob Ross I'm not confined by a fine brush.
