Chromatic scale. Chromatic scale: every key of one octave on the piano keyboard. 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. Chromatic instruments, such as the piano, are made to produce the chromatic scale, while ...
The diatonic scale notes (above) and the non-scale chromatic notes (below) [13] Medieval theorists defined scales in terms of the Greek tetrachords. The gamut was the series of pitches from which all the Medieval "scales" (or modes , strictly) notionally derive, and it may be thought of as constructed in a certain way from diatonic tetrachords.
Chromaticism. Chromaticism is a compositional technique interspersing the primary diatonic pitches and chords with other pitches of the chromatic scale. In simple terms, within each octave, diatonic music uses only seven different notes, rather than the twelve available on a standard piano keyboard.
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.
The twelve-tone technique—also known as dodecaphony, twelve-tone serialism, and (in British usage) twelve-note composition—is a method of musical composition.The technique is a means of ensuring that all 12 notes of the chromatic scale are sounded as often as one another in a piece of music while preventing the emphasis of any one note [3] through the use of tone rows, orderings of the 12 ...
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 (12 √ 2 ≈ 1.05946).
A measure of the width of each scale step provides a method to classify scales. For instance, in a chromatic scale each scale step represents a semitone interval, while a major scale is defined by the interval pattern W–W–H-W-W–W–H, where W stands for whole step (an interval spanning two semitones, e.g. from C to D), and H stands for ...
Thus, a 12-note chromatic scale adds 5 pitch classes in addition to the 7 lettered pitch classes. The following chart lists names used in different countries for the 12 pitch classes of a chromatic scale built on C. Their corresponding symbols are in parentheses.
