piano/violin

[Carl Meyer]

While reading all this interesting discussion this morning I suddenly
realized that  I've not noticed the use of an important word.

It's TRANSDUCER!!

A soundboard doing its job is transducing  (any of various devices that
transmit energy from one system to another).
Yes, it uses vibration as the means to do this and any random resonance in
the board makes it more efficient at the frequency of resonance.  The "Q" of
the resonance determines the efficiency at that point.

Words and their definitions are fascinating.

Antares,   You say there are three types of people?  I could add a few sub
categories I think

Regards to all,

Carl Meyer
