How to play A♭ diminished 7th chord on guitar
Shape 456464
Shape characteristics
Closed voicing
Every sounding string is fretted, with no open strings. Tight, controllable tone that responds well to palm muting and dynamic picking.
Mid-neck · fret 4-6
Balanced tone, with neither the ringing openness of first position nor the bright snap of the upper register. Common choice for rhythm work when you want a fuller, more compact sound.
Full six-string voicing
All six strings ring, giving you the biggest, most resonant version of this chord, ideal for strumming and solo acoustic contexts.
Bass: A♭ · Top: A♭
The root is in the bass, so the chord sounds grounded and stable. This is the natural starting voicing for most progressions.
Compared to Shape xb0a0a , this voicing uses an open chord and sits higher on the neck (starting at fret 10) and drops 1 string for a tighter, more compact sound.
