Extended chord - Wikipedia, the free encyclopedia (325 words) |
 | 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 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). |

 | Eleventh chords are made by adding a perfect 11th from the root on top of that, and thirteenth chords are made by adding a major thirteenth on top of that. |
 | Augmented seventh chords are formed by adding a minor seventh to an augmented triad, or alternatively by augmenting the 5th of an ordinary seventh chord. |
 | In a sus chord the third of the chord is replaced by another note – usually the 4th, sometimes the 2nd – with the original notion being that it should resolve by changing to the third, albeit a little late. |
