Extended chord

Dominant thirteenth extended chord: C–E–G–B♭–D–F–A playⓘ. The upper structure or extensions, i.e. notes beyond the seventh, in red.

In music, extended chords are tertian chords with notes beyond the seventh. Chords such as the Ninth, eleventh, and thirteenth chords are extended chords. The thirteenth is the furthest extension diatonically possible as, by that point, all seven tonal degrees are represented within the chord. In practice, however, extended chords do not typically use all the chord members: the fifth is often omitted, as well as the ninth and eleventh, unless they are altered to give a special texture.

Extended chords were rarely used in the Baroque era and are used more frequently in the Classical era. The Romantic era saw greatly increased use of extended harmony. Extended harmony prior to the 20th century usually has dominant function – as V9, V11, and V13, or V9/V, V13/ii etc.

Examples of the extended chords used as tonic harmonies include Wild Cherry's "Play That Funky Music" (either a dominant ninth or dominant thirteenth).
