The G minor chord is a very popular chord on the guitar. The chord actually contains two notes that can be played on open strings (G and D), which means that you can technically play the Gm chord as an open chord (see the first shape in the image below). However, the open version of Gm is somewhat awkward, and almost never used. Instead, Playing Gm as a bar chord on the 3rd fret, is a much more common way of playing the chord. 

Gm is the relative minor of B flat Major, which is a common key, especially in certain styles, such as Jazz.

G Minor Triads

Playing triads is a great way of exploring the minor chord and the guitar fretboard more generally. By arranging the notes of the chord systematically using permutations (root position, first inversion, second inversion), interesting and unique shapes and voicings are created. The three different voicings for the G minor triad are:

  • G minor Triad (Root Position) – G, Bb, D
  • G minor Triad (1st Inversion) – Bb, D, G
  • G minor Triad (2nd Inversion) – D, G, Bb

By playing these triads on two different groups of three strings, we can produce six different shapes.
