Sonic Submarine Proposal
This is a proposal for an experimental musical instrument/sound sculpture. This was inspired by the work of Marilyn Donadt Percussion/sculptor/artist.
The base would be a simple piece of plywood laminated up to being around 1” thick and large enough in diameter to keep the piece from tipping over when played.
The foot that would separate the main form from the base would be a piece of mild steel tubing. It would be glued into the center of the wooden base. It would be in turn brazed to the bottom of the resonance chamber.
The resonance chamber is to be fashioned out of two stainless steel mixing bowls. Right now I have 16’ bowls but varying size of the bowls on future variation would be interesting.
All resonance chambers would have a sounding hole in the bottom front.
Later pieces might use two tank ends of mild steel to get larger resonance chamber. It would probably be better to weld these together then to try to braze them.
Right now I have 3 variations in mind for the basic instrument. The differences between the 3 variations are primarily in the material of the central. All of the variations would have the central post go through a hole in the top bowl and be brazed on both the inside and outside of the bowl.
The first would use a brass rod about the size of my little finger in diameter.
Next would be a high carbon steel rod harden and about the size of my little finger in diameter.
Last would be a piece of 4” copper tubing
All variations can be played by by striking with a variety of drum sticks or mallets
About the width of my hand up the central post would be brazed a mild steel plate, approximately 4” X 1.5” X 14 gauge, with rounded corners.
This could be played by striking with fingers, by striking with a variety of drum sticks or mallets, rubbed with a rubber ball, or it can be shaken.
In an arc around the central post would be brazed a series of tuned bronze rods.This could be played by striking with fingers, by striking with a variety of drum sticks or mallets, rub with rosined fingers, or it can be bowed with a violin bow.
Future experimentation would be to take the base idea and add extension springs of 6’ to 12’. They would attached at one end to the steel plate near the leading edge on either side of the central post. The other end would be attached to a drum head. They would be held under tension. They could be played by by stroking with fingers, bowed with a violin bow or by playing any other part of the instrument.
A variation of this would be to tie one end of the springs to a thin gauge steel plate in a frame. Once again tension would have to be held.
Adding guitar strings of bass guitar strings in a similar manner would also be interesting.
