Editing Extended chord (section)

==Jazz, jazz fusion and funk==
[[Jazz]] from the 1930s onward, [[jazz fusion]] from the 1970s onward and [[funk]] all have been seen to use extended chords as a key part of their sound. In these genres, chords often include added ninths, elevenths and thirteenths as well as their altered variations. In jazz and jazz fusion, compositions consist of complex [[chord progression]]s in which many of the chords are extended chords and in which many of the [[dominant seventh]] chords are [[altered chord|altered]] extended chords (e.g., A<sup>7add9{{music|#}}11</sup> or D<sup>7{{music|b}}9{{music|#}}11</sup>). Funk also uses altered extended chords, but in this genre, pieces are usually based on a vamp on a single chord, because rhythm and [[groove (music)|groove]] are the key elements of the style. When extended chords are voiced in jazz or jazz fusion, the root and fifth are often omitted from the [[chord voicing]], because the root is played by the bass player.<ref>{{Cite web|title=Chord Extensions 9ths, 11ths & 13ths {{!}} Extended Jazz Piano Chords|url=https://www.pianogroove.com/jazz-piano-lessons/chord-extensions-9ths-11ths-13ths/|access-date=2021-04-23|website=PianoGroove.com|date=8 November 2016 |language=en-US}}</ref>
