Shape characteristics
Barre chord
Your first finger flattens across multiple strings at the same fret. Movable up and down the neck to any key without changing the shape.
Upper register · fret 9-10
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.
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: D · Top: C♯
An extended chord tone is in the bass, giving the voicing a distinctive colour beyond the standard inversions.

Frequently Asked Questions
What does "a09999" mean?
The sequence a09999 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 Amaj11/D shape anywhere else?
Yes! This specific layout is just one way to voice a Amaj11/D chord. You can find all other variations in our chord shape library for Amaj11/D. Most guitarists choose different shapes based on whether they want a "brighter" or "deeper" sound, or which chord they are transitioning from.
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.
