Q is all about transferrence of energy, at resonant frequencies Q is measured in Electrical terms as the ratio of "current in" (parallel ccts) to circulating current. There is preferrential gain in the frequency domain. Max gain and resonant frquency differ by a factor which also determines the value of Q - the losses in effect. In mechanical terms it is movement, move glass too far and it breaks.

in answer to your "likes" - is it because you can get a tune from G and only harmonies from Q's?

Barbershop anyone?
