Extended chord

In music extended chords are tertian chords (built from thirds) or triads with notes extended, or added, beyond the seventh, including all the thirds in between the seventh and the extended note. Thus ninth, eleventh, thirteenth, and all farther chords are extended chords.

In popular music and jazz music, these chords are often referred to as added note chords, and are referred to by the simple interval rather than the compound interval (i.e., "added sixth chord" as opposed to "thirteenth chord").

In practice however, extended chords do not typically use all the chord members; the fifth is often omitted, as are notes between the seventh and the highest note (i.e., the ninth is omitted in an eleventh chord, the ninth and eleventh are omitted in a thirteenth chord).

Extended chords are rarely seen in the Baroque era, and are uncommon in the Classical era. When used in the Romantic era, they were almost always found on the dominant scale degree (as V9, V11, and V13).
