12-tone equal temperament chromatic scale on C, one full octave ascending, notated only with sharps. Play ascending and descending ⓘ. 12 equal temperament (12-ET) [a] is the musical system that divides the octave into 12 parts, all of which are equally tempered (equally spaced) on a logarithmic scale, with a ratio equal to the 12th root of 2 (≈ 1.05946).
The chromatic scale is a musical scale with twelve pitches, each a semitone, also known as a half-step, above or below its adjacent pitches. As a result, in 12-tone equal temperament (the most common tuning in Western music), the chromatic scale covers all 12 of the available pitches. Thus, there is only one chromatic scale.

The circle of fifths in 12-tone equal temperament drawn within the chromatic circle as a star dodecagon [1] For any positive integer N , one can represent all of the equal-tempered pitch classes of N -tone equal temperament by the cyclic group of order N , or equivalently, the residue classes modulo twelve, Z/NZ.
12 tone equal temperament chromatic scale on C, one full octave ascending, notated only with sharps. Play ascending and descending ⓘ. An equal temperament is a musical temperament or tuning system that approximates just intervals by dividing an octave (or other interval) into steps such that the ratio of the frequencies of any adjacent pair of notes is the same.
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 4), tuned to 440 Hz (referred to as A440). [1] [2] Every octave is made of twelve steps called semitones.

In microtonal music, magic temperament is a regular temperament whose period is an octave and whose generator is an approximation to the 5/4 just major third. [1] [2] [3] In 12-tone equal temperament, three major thirds add up to an octave, since it tempers the interval 128/125 to a unison.
