Eleventh chord

Typically found in jazz, an eleventh chord also usually includes the seventh and ninth, and elements of the basic triad structure.

To reduce this dissonance the third is often omitted[4] (such as for example in the dominant eleventh chord that can be heard 52 seconds into the song "Sun King" on The Beatles' Abbey Road album), turning the chord into a suspended ninth chord (e.g. C9sus4, C–G–B♭–D–F), which can be also notated as Gm7/C.

[2] Another solution to this dissonance is altering the third or eleventh factor of the chord to turn the problematic minor ninth interval within the chord into a major ninth.

As its upper extensions (7th, 9th, 11th) constitute a triad, a dominant eleventh chord with the third and fifth omitted can be notated as a compound chord with a bass note.

The eleventh is usually retained as a common tone when the chord resolves to I or i.
