Question by Clarita Canela: How does a piano tuner use a tuning fork to adjust a piano wire to a certain fundamental frequency?
How does a piano tuner use a tuning fork to adjust a piano wire to a certain fundamental frequency?

It’s a physics question and for some reason I can’t get it through my head. Someone please explain it to me. I’d really appreciate it.

They use beat frequencies between the fork and the wire. For example, if the fork oscillates at 440 Hz, and the piano note at 441 Hz, there will be an audible beat note at the difference, 1 Hz. If the note is supposed to be 440 Hz, the tuner adjusts the tension while hitting the key until the beat note disappears.

Other methods, if the note is supposed to be 445 Hz, the tuner counts the beat notes and checks for a 5 hz beat note, ie, 5 per second.

You can also work with harmonics, and do other tricks to adjust various keys.
