A dolphin would likely play something more like a trombone with an articulating system of pipes that could be played through vigorous contortions of the body. Think playing a trombone but with a hula hooping/swimming motion. Perhaps a small lever could extend out to the dolphin flipper that would allow nuanced fine pitch control with lateral contortions of the dolphin’s flipper.
