How to play G augmented 7th flat 9th chord on guitar
Shape xaddcd
Shape characteristics
Partial barre
One finger presses two strings at the same fret. A lighter, less tiring grip than a full barre while still being fully movable.
Upper register · fret 10-13
Brighter, more focused tone with less low-end. Works well when layering over a bassist or second guitar, and integrates naturally with lead-line phrasing higher on the neck.
Five-string voicing
One string muted. Keeps a full low end without overlapping awkwardly with a bassist or second guitar.
Bass: G · Top: F
The root is in the bass, so the chord sounds grounded and stable. This is the natural starting voicing for most progressions.
Shape xadd0d is the closest alternative voicing. Try both to see which fits better.

Frequently Asked Questions
What does "xaddcd" mean?

- x means the string is muted or skipped entirely.
- 0 means the string is played "open" (without pressing over a fret).

Why do some strings have an 'x'?
