What does 440 Hz mean on a piano?
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}}\,}
Below you can find a list of frequencies of all the keys on a piano. Click on a row to hear the note played. Here are some key highlights from the frequency list below: The highest note on a standard piano has a frequency of 4186.009 Hz. It is a C. The lowest note on a standard piano has a frequency of 27.5 Hz. It is an A.
May 6, 2014 · 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 . I read for example here: http://en.wikipedia.org/wiki/Railsback_curve#The_Railsback_curve that the true pianos are not tunes in such ideal way, and the ...

Piano key frequencies. This is a. virtual keyboard. showing the absolute frequencies in hertz (cycles per second) of the notes on a modern piano (typically containing 88 keys) in twelve-tone equal temperament, with the 49th key, the fifth A (called A4), tuned to 440 Hz (referred to as A440).

The following equation gives the frequency of the th key, as shown in the table: f(n) = \left(\sqrt[ 12 ]{ 2 }\right) n -49 x 440 Hz (a' = A 4 = A440 is the 49th key on the idealized standard 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.
Tones and pitches. A piano can contain different numbers of keys since there are only twelve different tones, which are repeated with diverse pitches. A pitch is the frequency of the sound measured in hertz, but it is easier to think of low, mid and high ranges.
