You aren't the first to have the thought. You won't be the last. The idea
was patented in the early 80's, which amused me, because I'd thought of the
idea prior to that. After all, what the heck is a piano! Hold down the
sustain pedal, and that is exactly what you have. I used to use it to
resonate the organ which was in the same room.
