Upper Structures

Piano

In Jazz harmony triads are not often played as the standard voicing for a chord. However, when triads are combined with other notes they can be used to find interesting voicings that are easier to find....

The C7#11 chord (Lydian Dominant) has a distinctive sound because of the raised 11th. It is easily found by playing the Major triad one tone above the Root chord. The Triad or the Tritone can be inverted.

Un UPPER STRUCTURE can be defined as a TRIAD superimposed on a TRITONE. (A tritone is made up of three tones e.g. E-Bb). Upper structures referes to a simple technique of combining a Major or Minor triad with the 3rd and 7th of a Dominant 7th chord
