The following equation gives the frequency f (Hz) of the n th key on the idealized standard piano with the 49th key tuned to A 4 at 440 Hz: f ( n ) = ( 2 12 ) n − 49 × 440 Hz = 2 n − 49 12 × 440 Hz {\displaystyle f(n)=\left({\sqrt[{12}]{2}}\,\right)^{n-49}\times 440\,{\text{Hz}}\,=2^{\frac {n-49}{12}}\times 440\,{\text{Hz}}\,}
May 6, 2014 · What are the true frequencies of the piano keys? Asked 10 years ago. Modified 1 year, 9 months ago. Viewed 11k times. 16. In theory it is easy, to get the frequency of the note other than A4=440Hz you just multiply/divide 440Hz by the proper number. For example, to get A2, you divide by 4 and get A2=110Hz.

At the top end of the piano, moving over one key increases the frequency by over 200 Hz. What remains the same is the percent increase – as you move one key to the right, the new frequency is about 6 percent higher than the previous note.

The lowest frequency on a piano is 27.5 Hz, which is almost at the start of the human hearing range. However, the highest frequency on a piano is only 4186.01 Hz. Why is this the highest frequency on a piano?

The piano has 88 keys which span the frequency range 27.5 Hz (A0) to 4186 Hz (C8). The strings are sounded by hammer mechanisms which are activated by the keys. The relatively soft hammer structure, fashioned from pressurized wool, gives a dramatic attack to the tone without sounding harsh.
