minor/minor seventh chord
Component intervals from
minor triad with a minor seventh attached to it.[2]

For example, the minor seventh chord built on A, commonly

written
as A−7, has pitches A-C-E-G:

{ \new Staff \with{ \magnifyStaff #1.5 } \relative c' { \override Score.TimeSignature #'stencil = ##f <a c e g>1 } }

Minor/minor seventh chord

A seventh chord with a minor third, perfect fifth, and minor seventh is commonly called a minor seventh chord, but also sometimes a minor/minor seventh chord to distinguish it from the minor/major seventh chord discussed below. It can be represented as either as m7 or −7, or in integer notation, {0, 3, 7, 10}.

This chord occurs on different

scale degrees in different diatonic scales
:

  • In a
    ii–V–I turnaround
    is a minor seventh chord (ii7).

Example of tonic minor seventh chords include LaBelle's "Lady Marmalade", Roberta Flack's "Killing Me Softly with His Song", The Doobie Brothers' "Long Train Runnin'", Chic's "Le Freak", Lipps Inc.'s "Funkytown", and the Eagles' "One Of These Nights".[5]

The major sixth chord (major triad with an added major sixth) is an inversion of this chord.

Minor/major seventh chord

When the seventh note is a

written
as CmM7, has pitches C–E♭–G–B:

{ \new Staff \with{ \magnifyStaff #1.5 } \relative c' { \override Score.TimeSignature #'stencil = ##f <c es g b>1 } }

Its harmonic function is similar to that of a "normal" minor seventh, as is the minor seven flat five or half-diminished chord – but in each case, the altered tone (seventh or fifth, respectively) creates a different feeling which is exploited in modulations and to use leading-tones.

The minor seventh chord may also have its interval of minor seventh (between root and seventh degree, i.e.: C–B♭ in C–E♭–G–B♭) rewritten as an

enharmonic major second converge to unison or diverge to octave.[8]
