The 11 chord is an extended chord which includes the major triad with added notes of the 9th and 11th intervals. Commonly used in jazz, funk, and fusion music, the 11 chord adds depth and a complex texture to a harmonic progression. A well-voiced 11 chord maintains a balance between the core triad and the added intervals, allowing the 11th to enrich the chord without overpowering it. Guitarists need to be mindful of the added notes and avoid clashing with the root note to maintain sonic clarity. The 11 chord is often used as a substitution for a dominant 7th chord to create a more unresolved, suspended feel.
