Electrons in the key of F

This fellow plays the sound of a “nano-tube” at around 12:20 where with each electron added, the nano tube plays a note of the F minor scale.  https://youtu.be/wZzHnZzm_58

I’m just playing along with my guitar where my F is tuned to 345.6 Hz. You could try it on a guitar or a piano.

Further evidence that F (and the note a fifth below it, B-flat) are fundamental frequencies in the universe which become apparent to us through oddities like this nano-tube and my own weird encounter with the tone generator on my iPhone.
