The piano is part of an immensely complex coupled system which includes its environment.
All the parts are highly interactive, all seeking, as it were, to advance their own preferred modifications of the energy exchange.
This is especially so in the case of a piano, in which the moment of major energy input (the hammer strike) is relatively brief as compared to, say, the bowing of a violin.
[It might well be that in a piano with a mahogany plywood soundboard, the "resonance chamber" improves the sound, though probably not for the reasons given in the patent. At least it helps turn the sale!]
I had an emergency call from a college. They were setting up for the rededication of a restored historic building. Something was wrong: the damper pedal was stuck, and the piano movers couldn't fix it.
The piano was at the foot of a four story marble spiral staircase, and it sounded very much like a piano with the damper pedal stuck down!

Jim, I don't know what argument you're making, since you contradicted yourself.
In your example/demo energy was provided by the human. Provide is not produce.

< I have never seen music wire begin to vibrate on its own. . Therefore, I always thought it was the player that produced the energy.
Block dampers up on a grand with a live board. Remove yourself physically from the proximity of the piano and sing a tone or play a note on another piano. Listen to the combination of the board and strings, in sympathetic motion, jump into gear. Energy provided by frequency coupling from a distance.
