This is a list of the fundamental frequencies in hertz (cycles per second) of the keys of a modern 88-key standard or 108-key extended piano in twelve-tone equal temperament, with the 49th key, the fifth A (called A<sub>4</sub>), tuned to 440 Hz (referred to as A440). Every octave is made of twelve steps called semitones. A jump from the lowest semitone to the highest semitone in one octave doubles the frequency (for example, the fifth A is 440 Hz and the sixth A is 880 Hz). The frequency of a pitch is derived by multiplying (ascending) or dividing (descending) the frequency of the previous pitch by the twelfth root of two (approximately 1.059463). This deviation from equal temperament is graphically represented by the Railsback curve.
The following equation gives the frequency (Hz) of the <sup>th</sup> key on the idealized standard piano with the 49th key tuned to A<sub>4</sub> at 440 Hz:
:<math>
f(n) = \left(\sqrt[12]{2}\,\right)^{n-49} \times 440 \,\text{Hz}\, = 2^{\frac{n-49}{12 \times 440 \,\text{Hz}\,
</math>
where is shown in the table below.
