The major seventh chord, sometimes also called a Delta chord, can be written as maj 7, M 7, Δ, ⑦, etc. The "7" does not have to be superscripted, but if it is, then any alterations, added tones, or omissions are usually also superscripted. For example, the major seventh chord built on C, commonly written as Cmaj 7, has pitches C–E–G–B:
A minor major seventh chord, or minor/major seventh chord (also known as the Hitchcock Chord) is a seventh chord composed of a root, minor third, perfect fifth, and major seventh (1, ♭ 3, 5, and 7). It can be viewed as a minor triad with an additional major seventh. When using popular-music symbols, it is denoted by e.g. m (M7).
The harmonic minor scale (or Aeolian ♮7 scale) is a musical scale derived from the natural minor scale, with the minor seventh degree raised by one semitone to a major seventh, [2] [3] [4] creating an augmented second between the sixth and seventh degrees.
Note that this provides other ways of showing a ninth chord, for instance, C 7add 9, C 7add 2, or C 7/9. Generally however, this is shown as simply C 9 , which implies a seventh in the chord. Added tone chord notation is useful with seventh chords to indicate partial extended chords, for example, C 7add 13 , which indicates that the 13th is ...
When a musical key or key signature is referred to in a language other than English, that language may use the usual notation used in English (namely the letters A to G, along with translations of the words sharp, flat, major and minor in that language): languages which use the English system include Irish, Welsh, Hindi, Japanese (based on katakana in iroha order), Korean (based on hangul in ...
The most common chords are tertian, constructed using a sequence of major thirds (spanning 4 semitones) and/or minor thirds (3 semitones). Since there are 3 third intervals in a seventh chord (4 notes) and each can be major or minor, there are 7 possible permutations (the 8th one, consisted of four major thirds, results in a non-seventh augmented chord, since a major third equally divides the ...
In 24-tone equal temperament a supermajor seventh, semiaugmented seventh or, semidiminished octave, 23 quarter-tones, is 1150 cents (Play ⓘ). The small major seventh is a ratio of 9:5, [7] now identified as a just minor seventh. 35:18, or 1151.23 cents, is the ratio of the septimal semi-diminished octave. [8]
As musicologist Roger Kamien explains, "the crucial difference is that in the minor scale there is only a half step between '2nd and 3rd note' and between '5th and 6th note' as compared to the major scales where the difference between '3rd and 4th note' and between '7th and 8th note' is [a half step]." [1] This alteration in the third degree ...
