Lydian chromatic concept of tonal organization
Encyclopedia
The Lydian Chromatic Concept of Tonal Organization was written by George Russell
George Russell
George Allen Russell was an American jazz pianist, composer and theorist. He is considered one of the first jazz musicians to contribute to general music theory with a theory of harmony based on Jazz rather than European music, in his book, The Lydian Chromatic Concept of Tonal Organization...

 and is the founding text of the Lydian Chromatic Concept (LCC), or Lydian Chromatic Theory (LCT). The work postulates that all music is based on the tonal gravity of the Lydian mode
Lydian mode
The Lydian musical scale is a rising pattern of pitches comprising three whole tones, a semitone, two more whole tones, and a final semitone. This sequence of pitches roughly describes the fifth of the eight Gregorian modes, known as Mode V or the authentic mode on F, theoretically using B but in...

Deriving Lydian

Russell believed that dominant function was the driving force behind all harmonic motion. Russell focuses on the Lydian mode because it can be built with fifths. For instance, to construct a C lydian scale one could list the first seven tones on the circle of fifths
Circle of fifths
In music theory, the circle of fifths shows the relationships among the 12 tones of the chromatic scale, their corresponding key signatures, and the associated major and minor keys...

 starting with C, the desired tonic. This process would yield C, G, D, A, E, B, F. If these tones are voiced in the space of an octave, they form the Lydian mode (C, D, E, F, G, A, B). Additionally, Russell observed, when these tones are voiced in thirds they form the preferred form of a 13th chord.

Tonal gravity

Russell posits that tonal gravity emanated from the first seven tones of the lydian mode. As the player ventures further from the Lydian tonic however (and further up the circle of fifths), the tonal gravity shifts. For example, if notes further up the circle of fifths (e.g. 3) are used, the tonal gravity is probably shifting.

Impact

Russell's theory has had far reaching impact, especially in the realm of modal jazz. Art Farmer

. John Coltrane's modal jazz is usually analyzed using Russell's method. Additionally, many conservatories teach Russell's theory to varying degrees.
