An eleventh chord is an extended chord that includes a triad plus the seventh, ninth, and eleventh notes of the scale. Due to the number of notes in an eleventh chord, guitarists often omit certain notes, like the fifth or even the ninth, to make the chord more playable on the fretboard. By focusing on the essential tones—the root, third, seventh, and eleventh—guitarists can capture the chord’s harmonic essence without overcrowding the sound. Eleventh chords are popular in jazz and funk for their rich, layered quality.
