Is there some kind of resonance or something that happens at half/quarter that lets you identify it?

I experimented real quick and wasn't able to do a great job estimating half of a frequency from playing with the slider on the lower one. Wasn't _totally_ off, but nothing magical seemed to happen when I got to half.

Can you tune a guitar? I can hear it when the frequencies become small integer proportions like the octave (2x) and the fifth

I suppose I've never tried. Maybe it just requires some practice.
