What is that humming I hear??

Congrats to Gerald Eskelin for the ULTIMATE "high third" choir experiment.
Wow. I swear you have a little "gremlin" tuner standing behind that piano
and tuning the "E" lower and lower, bit by bit.

It's great you learned how to post stuff like that. I would also like to
learn someday... Also, the sound quality is great. I didn't realize,
though, that people could make sounds through their mouths like that... I
just assumed music was always made with oscillators (??)
