In standard jazz harmony, tritone substitution works because the two chords share two pitches that themselves are a tritone apart: namely, the third and the seventh of the chord, albeit reversed. [8] In a G 7 chord, the third is B and the seventh is F; in its tritone substitution, D ♭ 7, the third is F and the seventh is C ♭ (enharmonically ...
Jazz harmony is the theory and practice of how chords are used in jazz music. Jazz bears certain similarities to other practices in the tradition of Western harmony , such as many chord progressions , and the incorporation of the major and minor scales as a basis for chordal construction.
Also in jazz harmony, the tritone is both part of the dominant chord and its substitute dominant (also known as the sub V chord). Because they share the same tritone, they are possible substitutes for one another. This is known as a tritone substitution. The tritone substitution is one of the most common chord and improvisation devices in jazz.
The tritone substitution, an harmonic device common in jazz chord progressions where a dominant V chord is substituted with a bII7 chord (or a secondary dominant II7 chord with a bVI7 chord, etc.), whose common justification is the enharmonicity of the tritones of both chords (G7 has a B-F tritone whereas D♭7 has an enharmonic Cb-F tritone ...
The tritone substitution is widely used for V7 chords in the popular jazz chord progression "ii-V-I". In the key of C, this progression is "d minor, G7, C Major". With tritone substitution, this progression would become "d minor, D ♭ 7, C Major," which contains chromatic root movement. When performed by the bass player, this chromatic root ...
Example 1: Below, a common voicing used by jazz pianists is given for the chord C 7 ♯ 9 (C major chord with a minor 7th, and extended with an augmented 9th). In the lower stave the notes E ♮ and B ♭ are given. These form a tritone which defines the dominant sound, and are the major 3rd and minor 7th of the C 7 ♯ 9 chord.
In classical harmony, the chord is rarely seen spelled as a seventh chord and is instead most commonly found as the enharmonically equivalent French sixth chord. In jazz harmony, the dominant seventh flat five may be considered an altered chord, created by lowering the fifth of a dominant seventh chord, and may use the whole-tone scale, [1] as ...
