I can't think of any musical instruments that *are* harmonically
driven, unless you count a speaker driven by an amplified synthesizer.
Resonance would be a distinct drawback in a speaker.

Leigh, the trombone, trumpet, bugle and I suppose other brass are clearly
harmonically driven -- musicians please speak up here -- ie the lips must
vibrate at the frequency of the desired note -- or maybe at an
harmonic. The instrument is merely a resonant cavity to amplify the sound
made by the lips -- as opposed to the winds and reeds, which amplify broad
spectrum noise in the case of the reeds and define the frequency in the
case of the winds.

However I am not sure of any of this. (:-)
