Not at all. I 'just' disagree with your statement that the connection
is *never* made between resonances that are driven by sympathetic
vibrations and those that are driven by more esoteric inputs such as
'delta function' hammer blows or chaotic turbulence of wind
instruments.

I don't yet see the 'sympathetic vibrations' of the particle
scattering model, so I accept it as being an exception to your
requirement of sympathetic driving. Aeolian harp and vortex shedding
seem to me to be an adequate example of resonant driving.

I'm not yet ready to accept the Pedagogically Correct position that
it ain't resonance if it ain't driven by sympathetic vibrations.

Sorry to have hurt your feelings Leigh - really.
