Shape axabbb
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 10-11
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: D · Top: E♭
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 addbda , this voicing uses a partial barre and adds 1 more ringing string for a fuller sound.
