a good analogy. but that applies slightly differently.

basically, crystals are cut to oscillate at designed frequency, with
exceptions being those designed to vary with voltage.

true, but if frequency cut, they tend to reach designed resonance.

i did find a good lead in to crystals which refreshed my learning
from years ago at;

  https://en.wikipedia.org/wiki/Crystal_oscillator

more info relating to v/f swing near bottom;


https://en.wikipedia.org/wiki/Crystal_oscillator#Circuit_notations_and_abbreviations

[notable those with "VC" in name]

info on BIOS chip is at;

  https://en.wikipedia.org/wiki/BIOS

both of which tend towards 'off topic', but i thought it might
help others who may like to know more about the bios chip and
it's oscillator.
