Amaj911

Amaj911 is a chord symbol used in music notation to denote an A major harmony enriched with upper extensions. In practical terms, it is usually read as an A major seventh with both the ninth and the eleventh added, i.e., A–C#–E–G#–B–D. Because chord symbols are not universally standardized, performers may interpret the symbol in slightly different ways, and some charts simply treat Amaj911 as shorthand for Amaj9(11).

Voicings range from full, root-position shapes to compact, instrument-friendly forms. A common full voicing includes the notes A, C#, E, G#, B, and D in some arrangement. On guitar, players often omit the fifth or seventh to fit a particular texture while preserving the essential color of the 9th and 11th. Keyboard voicings frequently place the 9th and 11th above the essential triadic and seventh tones to achieve a lush texture.

Usage and context: The sound is bright and rich, making it suitable for jazz ballads, fusion passages, and sophisticated pop sections. It typically appears in progressions where the tonic chord seeks extra color before resolving to a dominant or subdominant area, or when creating an extended harmony in improvisational settings. The symbol’s exact interpretation can vary by arranger, ensemble, or genre.

Notes: Amaj911 is not as widely standardized as other chord symbols; readers should check the intended voicing in the specific chart or with the performer.
