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 ...

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.
For instance, in the C major scale, G is the fifth note of the scale, and the seventh chord built on G is the dominant seventh chord, G 7 (shown above). In this chord, F is a minor seventh above G. In Roman numeral analysis, G 7 would be represented as V 7 in the key of C major.
To analyze seventh chords indicate the quality of the triad; major: I, minor: ii, half-diminished: vii ø, or augmented: III+; and the quality of the seventh; same: 7, or different: 7 M or 7 m. [2] With chord letters used to indicate the root and chord quality, and add 7, thus a seventh chord on ii in C major (minor minor seventh) would be d 7. [1]
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:
Diminished seventh chords may also be rooted on scale degrees other than the leading-tone, either as secondary function chords temporarily borrowed from other keys, or as appoggiatura chords: a chord rooted on the raised second scale degree (D ♯ –F ♯ –A–C in the key of C) acts as an appoggiatura to the tonic (C major) chord, and one ...
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 ...
