Step 7VARIATIONS ON THE STETHOSCOPE INSTRUMENT THEME
What you put together depends on what you find to work with. You will probably not find the same ball and typewriter parts, but a different combination of things can be just as interesting.
The attached photos are of stethoscope sculptures I made many years ago.
The one on the truck bed had the stethoscope listening to the pipe, an old drive shaft. It had an acoustic "microphone" that conducted the voice to the inside of the pipe. One flat array of rods of different lengths was struck with small drumsticks. A curved array of rods was played with a violin bow and sounded like electronic feedback. There was also a set of strings attached to the base pipe that sounded like a harp.
The other instrument, played by a friend, had a gurgle sound made by blowing air into a reservoir of liquid inside it. A "dandelion" shape of rods on top sounded similar to The Secretary's Nightmare. It also had a squeaky wheel.
