G minor 7th chord on bass (Gm7)

Why it sounds like that

G minor 7th is built from the formula 1, ♭3, 5, ♭7. The minor 7th interval from G to F gives the chord its mellow, jazzy quality. Compare it with G minor, which lacks the F.

What goes wrong with G minor 7th?

• Letting the pinky collapse and buzz the 3rd string.
• Allowing the middle finger to touch the 1st string and mute the D.
• Strumming before all fingers are firmly placed, causing a dead note.

When to use it

G minor 7th functions as the vi chord in B♭ major, appearing in progressions like B♭–F–Gm–E♭ (I–V–vi–IV). It suits jazz, blues, and soul, often paired with B♭ major and E♭ major.

Changing to and from G minor 7th

• Sliding the shape down two frets to the 1st fret gives F minor 7th.
• From G minor 7th, move the pinky from the 5th fret to the 6th fret on the A string to form A♭ minor 7th.

Which voicing to use

Use the 3rd-fret voicing for a root-position G minor 7th with a low G. The Gm7/D inversion at the 10th fret places the fifth in the bass for a smoother sound, while the Gm7/F inversion at the 1st fret puts the seventh in the bass and is easier to play.
