It is unlikely that any two collections of found objects will be the same, so the finished instruments will also be different and involve user creativity to solve unique mounting problems that may arise. Some collections may use legs and sit on the floor. Some may be mounted to a wall, or hang from a ceiling, or involve any combination of the above.
The objects are mounted in space so that they do not touch, and will vibrate independently of each other to avoid buzzing or rattling sounds. Only available materials limit size and the variety of sounds that can be produced. "The Phoenix" can be played with drumsticks of metal or wood.
Step 1: THE BASE
This particular base is half attached to a table edge and half suspended by wires from overhead in order to adapt to its unique location in my house. PVC pipe legs could be used instead to make it a free-standing instrument.
