Piano keys and their frequencies

Hope209 · 30th June 2006

Is there a chart anywhere online that shows 88 piano keys and their corresponding frequencies?

Awesome, thank you

I came across this great little program.

It calculates tempo delay, ms to samples, notes to freq etc.

Below is my contribution, but it's important to take such charts with a grain of salt. The lowest note on a piano may have a fundamental pitch of 27.5 Hz, but I promise you there is zilch that low. Even "normal" low notes like the A notes at 55 and 110 Hz have very little content at their fundamental pitch. It's mostly second harmonic, and the lower you go, the less there is of that too. I once did an FFT (spectrum analysis) on a low piano note played loudly (bright sound), and the response was more or less a straight horizontal line.

Thanks so much for posting this! You just saved me having to bring in the musician to do another take! I was getting alot of harsh tone around key 61 A at 880Hz

So could you have a track that is muddy at 165 hz, but that doesn't have an E in it? Frequncies are kind of different than notes in that respect, aren't they? For example you could have a lot of junk in the drums, or room sounds, though (most of the times) they're not tones. What makes a note?

I believe that has to do with the fundimental frequency. The same way that a plucked E string on a guitar will produce all of the frequencies in our hearing range at different amplitudes. The E note comes from the fundimental or the most dominant frequency. The recognizable 'guitar' sound comes from the relationship between the harmonics that the fundimental excites.
...I think.
