Guitar chords in the key of G minor

The seven chords of G minor are Gm, Adim, Bb, Cm, Dm, Eb, F. Each one has a job in the key, and each tends towards particular chords next.

• Gm, the tonic of G minor. Usually goes to Cm or Dm: the departure, carrying the flat 6th with it.
• Adim, the supertonic of G minor. Usually goes to Dm: roots falling a fifth: the minor key’s ii–V.
• Bb, the mediant of G minor. Usually goes to Eb or F: a fourth up inside the relative major.
• Cm, the subdominant of G minor. Usually goes to Dm: subdominant into dominant, the cadence the minor key borrows from major.
• Dm, the dominant of G minor. Usually goes to Gm: the leading tone rises into the minor tonic.
• Eb, the submediant of G minor. Usually goes to F or Cm: the Aeolian cadence: ♭VI–♭VII–i closes the key with no dominant at all.
• F, the subtonic of G minor. Usually goes to Gm or Bb: a whole tone into the tonic, no leading tone, so it arrives rather than resolves.
