Basically, the Ron Brown Jazz Improvisation Method (RBJIM) reveals tonal relationships that reduce the overall complexity of jazz improvisation providing the performer with a technique and direct guidance to access personal creativity. In conjunction, there are three families of chords that compose the vast majority of music in general. First, the major chord is considered to possess a pretty sound and can serve as a resolving group of notes, for example, F major 7/13 (FACED). Secondly, the minor chord has been expressed to portray a sort of sad feeling, for example D minor 9 (DFACE). Finally, the dominant chord creates tension, even notable in classical music V-I. However, there are eight dominant variations most commonly used in jazz and this (RBJIM) demonstrates and reduces two chords for the price of one. Basically, the main dominant voice is dominant 9/13 ((FABE).
