This table lists pitches with their ISO note names, frequencies (in Hertz), and MIDI note numbers. Frequencies are the standard ones, with A-440 and equal temperament. In equal temperament, an interval of 1 semitone has a frequency ratio of 2^(1/12), or ca. 1.05946 : 1. Since A-440 is MIDI note number 69, the frequency in Hertz of note number m is therefore

    freq = 440 * 2^((m-69)/12)

*PL, *PH = the lowest and highest notes of the modern piano (except for a few, notably certain Boesendorfers, that go down to F0 or even C0).
*MC = middle C.
