Extended chord
In music, extended chords are certain Chord (music), chords (built from third (chord), thirds) or triad (music), triads with notes ''extended'', or added, beyond the seventh (chord), seventh. Ninth chord, Ninth, Eleventh chord, eleventh, and Thirteenth chord, thirteenth chords are extended chords. The thirteenth is the farthest extension diatonic and chromatic, diatonically possible as, by that point, all seven tonality, tonal degree (music), degrees are represented within the chord (the next extension, the fifteenth, is the same as the root of the chord). In practice however, extended chords do not typically use all the factor (chord), chord members; when it is not altered, the fifth is often omitted, as are notes between the seventh and the highest note (i.e., the ninth is often omitted in an eleventh chord; the ninth and eleventh are usually omitted in a thirteenth chord), unless they are altered to give a special texture.

''Materials and Concepts in Jazz Improvisation'', p.20. Examples Example 1: Below, a common voicing used by jazz pianists is given for the chord C79 (C major chord with a minor 7th, and extended with an augmented 9th). In the lower stave the notes E and B are given. These form a tritone which defines the dominant chord, dominant sound, and are the major 3rd and minor 7th of the C79 chord. In the upper stave the notes E, G, and B are given together: these form an E major triad. This E major triad is what would be called the upper structure. Considered in relation to the root C, the notes of this E major triad function, respectively, as the sharpened ninth (the root of the E major chord), ...
