The indie rock band Brunettes Shoot Blondes spent 3 years building a 20-piece hybrid instrument to be played by 2 musicians: The characteristic is that the instrument is completely mechanical and has no electronic component! Here are some real Music Makers.
Many musicians live a sort of “Unsustainable lightness of playing”, misquoting an old Milan Kundera’s book. Which of course is euphemistic and sarcastic at the same time. Because “playing” is never easy, even when you learn it.
