![]() 3-limit just intonation) the chromatic scale is tuned as follows, in perfect fifths from G ♭ to A ♯ centered on D (in bold) (G ♭–D ♭–A ♭–E ♭–B ♭–F–C–G– D–A–E–B–F ♯–C ♯–G ♯–D ♯–A ♯), with sharps higher than their enharmonic flats (cents rounded to one decimal): Many other tuning systems, developed in the ensuing centuries, share a similar asymmetry. Thus, the scale is not perfectly symmetric. Due to a different tuning technique, the twelve semitones in this scale have two slightly different sizes. The most common conception of the chromatic scale before the 13th century was the Pythagorean chromatic scale ( Play ⓘ). Tone rows, orderings used in the twelve-tone technique, are often considered this way due to the increased ease of comparing inverse intervals and forms ( inversional equivalence). The rising scale is Do, Di, Re, Ri, Mi, Fa, Fi, Sol, Si, La, Li, Ti and the descending is Ti, Te/Ta, La, Le/Lo, Sol, Se, Fa, Mi, Me/Ma, Re, Ra, Do, However, once 0 is given to a note, due to octave equivalence, the chromatic scale may be indicated unambiguously by the numbers 0-11 mod twelve. Similarly, some notes of the chromatic scale have enharmonic equivalents in solfege. It is also notated so that no scale degree is used more than twice in succession (for instance, G ♭ – G ♮ – G ♯). In general, the chromatic scale is usually notated with sharp signs when ascending and flat signs when descending. Its spelling is, however, often dependent upon major or minor key signatures and whether the scale is ascending or descending. The chromatic scale has no set enharmonic spelling that is always used. ![]() Roger Kamien (1976) Notation The circle of fifths drawn within the chromatic circle as a star dodecagram. The chromatic scale.is a series of half steps which comprises all the pitches of our equal-tempered system. As a result, the notes of an equal-tempered chromatic scale are equally-spaced. In equal temperament, all the semitones have the same size (100 cents), and there are twelve semitones in an octave (1200 cents). 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. 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. While the chromatic scale is fundamental in western music theory, it is seldom directly used in its entirety in musical compositions or improvisation. Most music uses subsets of the chromatic scale such as diatonic scales. Chromatic instruments, such as the piano, are made to produce the chromatic scale, while other instruments capable of continuously variable pitch, such as the trombone and violin, can also produce microtones, or notes between those available on a piano. The chromatic scale (or twelve-tone scale) is a set of twelve pitches (more completely, pitch classes) used in tonal music, with notes separated by the interval of a semitone.
