Ab dim position 1 guitar chord diagram

Abdim, the Ab diminished chord, is spelled Ab, Cb and Ebb. The lowest voicing starts at fret 3 and the highest reaches fret 13.

Compared with a minor triad only one note changes: the fifth drops by a semitone. Looking for a scale to play over it? The Ab whole-half scale contains all three notes of Abdim. Cb and Ebb are theoretical notes, which is why the same sound is also written G#dim. The logic of stacking thirds is explained in how chords are built.

In sound, Abdim matches the vii chord of A major, which that key spells with other letters. Strum a shape in front of your microphone and the chord player at the top shows which strings ring and which are muted.

Ab diminished guitar chord is also written as Abdim, Ab°, Abm(b5) or Abmb5.
