Gm7

Gm7, or G minor seventh, is a four-note chord built from the root G, a minor third Bb, a perfect fifth D, and a minor seventh F. In practice it is voiced most often as G-Bb-D-F, though other voicings place these notes in different orders (for example Bb-D-F-G or D-F-G-Bb).

The chord is diatonic to G natural minor and to the G Dorian mode, and it commonly appears in functional harmony as the ii7 chord in the key of F major (Gm7–C7–F). In a minor-key context, Gm7 can function as i7 when using the natural minor scale, and it is frequently used in modal or jazz progressions for its smooth predominant color.

In jazz and pop, Gm7 serves as a versatile color chord that can lead to the dominant (C7) or to other chords in minor-key progressions. Its quality and voice-leading options make it a common building block in both harmonic and melodic contexts, supporting gentle movement between tones and facilitating smooth bass lines.

Notational notes: Gm7 is also written as G-7 or Gmin7. A common alteration is Gm(maj7), which raises the seventh to F#, yielding G–Bb–D–F#. The chord can be derived from the G natural minor scale (G-A-Bb-C-D-Eb-F) or the G Dorian mode (G-A-Bb-C-D-E-F).
