The Ab minor chord is most commonly played as a bar chord. The chord itself contains the note B, which means the chord can technically be played as an open chord (see the first shape in the image below), but this is not a common way of playing the chord, even if it is the easiest.

The Abm chord is enharmonically the same as G#m.

Ab 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 A flat minor triad are:

  • Ab minor Triad (Root Position) – Ab, C, Eb
  • Ab minor Triad (1st Inversion) – C, Eb, Ab
  • Ab minor Triad (2nd Inversion) – Eb, Ab, C

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