Gbm/A Chord (Gb minor Over A) – 10 Ways to Play on the Guitar

The Gbm/A (Gb minor over A) chord is a G flat minor chord, with the A (the b3) as the bass note. Note that A is the same note as Bbb (B double flat). Technically, the ‘A’ in this chord is a Bbb, but referring to the note as A is much simpler (even if technically incorrect).

The chord is also referred to as Gbm over A, or Gbm ‘slash’ A, or simply, G flat minor with an A in the bass.

Technically, the Gb minor chord with the A in the bass is a second inversion Gb minor chord.

Some Gbm/A Chord Theory and Info

  • The Gbm/A chord contains the notes A, Gb and Db.
  • It is a G flat minor chord with an A in the bass.
  • The root note of Gbm/A is Gb, the bass note is A.
  • The Gbm/A chord is very similar to the A6 chord (which is the same as Bbb6), and they are often used interchangeably. The only difference between the two chords is that the A6 chord can also include the E note (same as Fb), which is the 5th of A. Including the E note in Gbm/A would make it a Gbm7/A, as the E (Fb) is the b7 note.
