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 aug^M7, +^M7, +^Δ7, M^{7^♯5}, M^7(♯5), M^7/♯5, M⁷⁺⁵, maj+⁷, Δ+⁷, etc. For example, the augmented major seventh chord built on A♭, written as A♭aug^M7, has pitches A♭-C-E-G:

${ \override Score.TimeSignature #'stencil = ##f \relative c' { \clef treble \time 4/4 \key c \major <as c e g>1 } }$

The chord can be represented by the integer notation {0, 4, 8, 11}.

The augmented major seventh chord is associated with the augmented scale^[1] (see jazz scale and chord-scale system). This chord also comes from the third mode of both the harmonic minor and the melodic minor scales. For example, the third mode of the A melodic minor scale outlines an augmented major seventh chord, as shown below.

${ \override Score.TimeSignature #'stencil = ##f \relative c' { \clef treble \time 7/4 \key a \minor \once \override NoteHead.color = #red c4^\markup { "3rd mode of A melodic minor scale" } d \once \override NoteHead.color = #red e fis \once \override NoteHead.color = #red gis a \once \override NoteHead.color = #red b c2 } }$

As with dominant seventh chords, nondominant seventh chords including the augmented major seventh usually progress according to the circle, thus III+^M7 resolves to vi or VI.^[2] For example, in the key of A minor, C maj^7♯5 usually resolves to F.
