Human hearing

second, putting it 17 octaves above what human ears take for music.

This doesn't add up. Using 20,000 Hz as a base frequency, 40 million Hz is
only 10.97 octaves higher. Perhaps the writer misunderstood what the
Cornell
people were telling him, since 40 million Hz is 16.47 octaves above A =
440
Hz, which is almost 17 octaves. The note would be somewhere in between a D
and a D#. I don't think it would harmonize well with the Bb of the black
hole. I wonder though if 40 million is the exact figure, or if it's
rounded.
That would affect the value of the note.

And they could "bend" the note by heating the "string" with the laser beam.

Hey, you might be on to something here. Perhaps the 40 million Hz tone is the
nanoguitar's "blue note".

This may be the best invention ever for guitar!

Good point.
