The term chromatic progression is used in three senses: Movement between harmonies that are not elements of any common diatonic system (that is, not of the same diatonic scale: movement from D–F–A to D ♯ –F ♯ –A, for example). [38] The same as the second sense of chromatic inflection, above. [39]
Short cyclical progressions may be derived by selecting a sequence of chords from the series completing a circle from the tonic through all seven diatonic chords: [15] I–IV–vii o –iii–vi–ii–V–I. This type of progression was much used by classical composers, who introduced increasingly subtle inflections.
Chromatic fourth: lament bass bassline in Dm (D–C ♯ –C(♮)–B–B ♭ –A) The diatonic scale notes (above) and the non-scale chromatic notes (below) [1] 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 ...
Modern musical keyboards are designed so that the white-key notes form a diatonic scale, though transpositions of this diatonic scale require one or more black keys. A diatonic scale can be also described as two tetrachords separated by a whole tone. In musical set theory, Allen Forte classifies diatonic scales as set form 7–35.
The diatonic circle of fifths is the circle of fifths encompassing only members of the diatonic scale. Therefore, it contains a diminished fifth, in C major between B and F. See structure implies multiplicity. The circle progression is commonly a circle of fifths through the diatonic chords, including one diminished chord.
I–V–vi–IV progression in C Play ⓘ vi–IV–I–V progression in C Play ⓘ The I–V–vi–IV progression is a common chord progression popular across several music genres. It uses the I, V, vi, and IV chords of the diatonic scale. For example, in the key of C major, this progression would be C–G–Am–F. [1] Rotations include:
The diatonic genus is composed of tones and semitones, the chromatic genus is composed of semitones and a minor third, the enharmonic genus consists of a major third and two quarter-tones or diesis. [16] Within these basic forms, the intervals of the chromatic and diatonic genera were varied further by three and two "shades" (chroai ...
The concept of harmonic function originates in theories about just intonation.It was realized that three perfect major triads, distant from each other by a perfect fifth, produced the seven degrees of the major scale in one of the possible forms of just intonation: for instance, the triads F–A–C, C–E–G and G–B–D (subdominant, tonic, and dominant respectively) produce the seven ...
