Here’s a prototype of a trumpet that I’ve concieved. It’s based on an idea I got from a sound sculpture I read about that was a trombone with a single input and multiple outputs. This is a trumpet with multiple inputs and a single output, to be played by two people. Andy Frobig helped put this thing together for me, and, once a few technical issues are overcome, there will certainly be more models (and some vidoes) coming soon. For other cornerstones of practicality like this, waste some time at noisejunk.com
The End.
