I made this kalimba (a part of the lamellophone family), from some leaf-rake tines and hacksaw blades. Alternatively, I have used car dipsticks, road-sweeper bristles, bicycle spokes, windshield wipers, and sewer springs before. You can make anything create sound! An added bonus when you invent a new instrument: you are instantly the best-’name instrument here’-player in the world.
