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 music, an augmented major seventh chord or major seventh sharp five chord is a seventh chord composed of a root, major third, augmented fifth, and major seventh (1, 3, ♯ 5, 7). It can be viewed as an augmented triad with an additional major seventh. When using popular-music symbols, it is denoted by e.g. + Δ 7.

Not including the root motion, there is only a one-note difference between a half-diminished seventh chord and a V 7 chord with a flat ninth. Since it is built on the diatonic II chord of the minor scale, most of the time the II-V pattern resolves to a minor tonic (such as in the progression D ø 7 – G 7 ♭ 9 – Cm), but there are also ...

Diminished major seventh chords are very dissonant, containing the dissonant intervals of the tritone and the major seventh.They are frequently encountered, especially in jazz, as a diminished seventh chord with an appoggiatura [citation needed], especially when the melody has the leading note of the given chord: the ability to resolve this dissonance smoothly to a diatonic triad with the same ...
