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:
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 harmonic analysis and on lead sheets, a C major chord can be notated as C, CM, CΔ, or Cmaj. A major triad is represented by the integer notation {0, 4, 7}. A major triad can also be described by its intervals: the interval between the bottom and middle notes is a major third, and the interval between the middle and top notes is a minor third.
Other chord qualities such as major sevenths, suspended chords, and dominant sevenths use familiar symbols: 4 Δ 7 5 sus 5 7 1 would stand for F Δ 7 G sus G 7 C in the key of C, or E ♭ Δ 7 F sus F 7 B ♭ in the key of B ♭. A 2 means "add 2" or "add 9". Chord inversions and chords with other altered bass notes are notated analogously to ...
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).
Harmonic minor scale. 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. Thus, a harmonic minor scale is represented by the following ...
