I didn’t have time to scavenge junk for Scrapyard Challenge, luckily, I was able to pick up a used umbrella while walking to the subway station, and that was what we used.
We drew inspiration from the mechanics of the music box, where the music played is pre-printed onto a cylinder plate in the form of pins. We created a pattern using tin foil, which acts as the music sheet. The pattern is circular, with multiple rings, each ring separate from the others with breaks of black tape in them. This was designed according to the possible movements of the umbrella. By pulling the umbrella up and down, the “claws” expand, respectively touching each circle and playing different tones. By spinning the umbrella, due to the breaks, beats can be created.
I’d never made anything like this before, and I was not sure if the idea would work. Fortunately, things turned out, and we were able to make “sounds” quite affectively. You can view a video documentation of our working instrument here.
