I've seen lots of dumb instruments. Not just in how they play or look but what they are made of. The piano is a string instrument with keys, I mean who thought of that, it's a massive instrument, it weighs a ton, and it's expensive. It's just the worlds most cumbersome harp with a different interface. How does one began to invent an instrument like that? It's just plain stupid. Don't even get me started on the tambourine. You can't even really play the dumb thing it's just a funny maraca, and the triangle, really? Their are so many dumb instruments it's ridiculous. Which instrument do you think is the dumbest and why.
