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.
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 ...
If the original chord in a song is G7 (G, B, D, F), the tritone substitution would be D ♭ 7 (D ♭, F, A ♭, C ♭). Note that the 3rd and 7th notes of the G7 chord are found in the D ♭ 7 chord (albeit with a change of role). The tritone substitution is widely used for V7 chords in the popular jazz chord progression "ii-V-I".
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.

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 ...

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.
