This chord features a minor seventh with an added major 11th (also referred to as a raised 11th), which is essentially a major fourth above the root note. Unlike the typical minor 11th chord, the major 11th interval gives this chord an unusual and captivating sound by juxtaposing both minor and major tensions. In terms of structure, starting from the root, the mmaj11 chord includes the following intervals: - Root - Minor third - Perfect fifth - Major seventh - Major second (or ninth) - Major fourth (or 11th) When playing an mmaj11 chord on guitar, players should consider voicing options that emphasize its distinct qualities and adjust their finger positioning to efficiently bring out its expressive sonic texture. This chord works well in many musical contexts, particularly in jazz and contemporary styles, where harmonic richness and intricate voicings are celebrated. Understanding its role in progressions and the emotional character it conveys will expand a player's harmonic vocabulary and enhance their ability to evoke particular musical atmospheres.
