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}}\,}
Opting for an appropriate reference pitch is paramount for attaining meticulous tuning. A frequently used reference pitch is A4, resonating at 440 Hz. Employ a digital piano, a tuning fork, or a piano tuning app with a steadfast pitch to establish the reference tone.

It is generally recommended to tune your piano at least twice a year. However, this frequency of tuning can vary based on usage, if the piano has been moved, or if the piano is new—as the strings and wood adjust to tension and environmental conditions.
May 6, 2014 · What are the true frequencies of the piano keys? Asked 10 years ago. Modified 1 year, 10 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.

Then tune A3-E4 in a contracted 5th; by tuning E4 slightly flat until you hear a beat of about 1 Hz. The contracted 5th should beat a little under 1 Hz at the bottom of the muted range ( A3) and about 1.5 Hz near the top. The beat frequencies of the 5ths should increase smoothly with increasing pitch.
