Mixed-interval chords from the opening to Arnold Schoenberg's Klavierstück Op. 33a [1] (Play ⓘ). In music a mixed-interval chord is a chord not characterized by one consistent interval. Chords characterized by one consistent interval, or primarily but with alterations, are equal-interval chords.
The size of an interval between two notes may be measured by the ratio of their frequencies.When a musical instrument is tuned using a just intonation tuning system, the size of the main intervals can be expressed by small-integer ratios, such as 1:1 (), 2:1 (), 5:3 (major sixth), 3:2 (perfect fifth), 4:3 (perfect fourth), 5:4 (major third), 6:5 (minor third).

All-interval tetrachords (Play ⓘ). An all-interval tetrachord is a tetrachord, a collection of four pitch classes, containing all six interval classes. [1] There are only two possible all-interval tetrachords (to within inversion), when expressed in prime form. In set theory notation, these are [0,1,4,6] (4-Z15) [2] and [0,1,3,7] (4-Z29). [3]
Klein chose the name Mutterakkord in order to avoid a longer term such as all-interval twelve-tone row and because it is a chord which unites all other chords by containing them within itself. [12] The Mother chord row was also used by Alban Berg in his Lyric Suite (1926) and in his second setting of Theodor Storm's poem Schliesse mir die Augen ...
A guitarist performing a C chord with G bass. In Western music theory, a chord is a group [a] of notes played together for their harmonic consonance or dissonance.The most basic type of chord is a triad, so called because it consists of three distinct notes: the root note along with intervals of a third and a fifth above the root note. [1]
The words derive from Latin words meaning "large" and "small," and were originally applied to the intervals between notes, which may be larger or smaller depending on how many semitones (half-steps) they contain. Chords and scales are described as major or minor when they contain the corresponding intervals, usually major or minor thirds.
