How to play G dominant 7th flat 9th chord on guitar
Shape xacd0d
Shape characteristics
Open chord
Uses one or more open strings, giving the chord a bright, resonant ring and making it easier to hold for long passages.
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.

Frequently Asked Questions
What does "xacd0d" mean?
The sequence xacd0d is a highly compact guitar chord notation. It represents the fret played on each of the 6 strings, reading left-to-right from the thickest (lowest pitch) string to the thinnest (highest pitch) string: E, A, D, G, B, e.
- x means the string is muted or skipped entirely.
- 0 means the string is played "open" (without pressing over a fret).
- 1-9 represent standard fret numbers 1 to 9.
- a, b, c... represent frets 10, 11, 12, and higher (where a=10, b=11, c=12).
Can I play this G dominant 7th flat 9th shape anywhere else?
Yes! This specific layout is just one way to voice a G dominant 7th flat 9th chord. You can find all other variations in our chord shape library for G dominant 7th flat 9th. Most guitarists choose different shapes based on whether they want a "brighter" or "deeper" sound, or which chord they are transitioning from.
Why do some strings have an 'x'?
Strings marked with an 'x' should not ring out. These notes are excluded because they don't belong to the G dominant 7th flat 9th chord or would clash with this specific voicing. You can mute these strings by lightly touching them with a finger that is already pressing a neighboring fret.
How do I stop my fingers from buzzing?
Since this shape uses open strings (marked with '0'), make sure your fingers are arched like a "claw" so they don't accidentally brush against the open strings. Press down firmly just behind the metal fret wires for the clearest sound.
