Editing Upper structure (section)

==Examples==

'''Example 1''': Below, a common voicing used by jazz pianists is given for the chord C<sup>7{{music|#}}9</sup> (C major chord with a minor 7th, and extended with an augmented 9th).

In the lower stave the notes E{{music|natural}} and B{{music|b}} are given. These form a tritone which defines the [[dominant chord|dominant]] sound, and are the major 3rd and minor 7th of the C<sup>7{{music|#}}9</sup> chord. 

In the upper stave the notes E{{music|b}}, G, and B{{music|b}} are given together: these form an E{{music|b}} major triad.

This E{{music|b}} major triad is what would be called the upper structure. Considered in relation to the root C, the notes of this E{{music|b}} major triad function, respectively, as the sharpened ninth (the root of the E{{music|b}} major chord), fifth, and seventh in relation to that root. 

(Note: the root C is omitted here, and is often done so by jazz pianists for ease of playing, or because a bass player is present.)

'''Example 2''': The following example illustrates the notes of an F{{music|#}} minor triad functioning as part of a C<sup>13{{music|b}}9{{music|#}}11</sup> chord (C major chord with a minor 7th, minor 9th, augmented 11th, and major 13th):

In relation to the root of C, the C{{music|#}} ([[enharmonic]] with D{{music|b}}) functions as the minor 9th, the F{{music|#}} as the augmented 11th, and the A as the major 13th, respectively.
