In jazz music, the lydian chord is the major 7♯11 chord, [1] or ♯11 chord, the chord built on the first degree of the Lydian mode, the sharp eleventh being a compound augmented fourth. This chord, built on C, is shown below.
This is described as "beautiful" and "modern sounding." [1] The notes that make up the Lydian chord represent five of the seven notes of the Lydian mode, and the ♯11 at the top of the chord is the ♯4 (one octave higher) that distinguishes the Lydian mode from the major scale.
Major 7♯11 may also refer to the Lydian augmented chord, an augmented seventh chord with augmented fourth appearing in the Lydian augmented scale. [2]
In a chord chart the notation, "Lydian" indicates a major family chord with an added augmented eleventh, including maj7♯11, add9♯11, and 6♯11. [1]
Lydian chords may function as subdominants or substitutes for the tonic in major keys. [3] The interval of the sixth is used even though it is described after other compound intervals, and perhaps should also be a compound interval (i.e., thirteenth).[ vague] The interval is considered to be the compound interval (i.e., thirteenth) when appearing with the Maj7th in the initial chord.
The dominant 7♯11 or Lydian dominant (C7♯11) comprises the notes:
Basing this chord on the pitch C results in the pitches:
The same chord type may also be voiced:
This voicing omits the perfect fifth (G) and raises the major ninth (D) by an octave. The augmented eleventh (F♯) is also played twice in two different registers. This is known as " doubling".
