The conventional G7 chord is replaced in bars 3 and 4 of the following example with a D♭7 chord, with a diminished fifth (G♮ as the enharmonic equivalent of A); a chord otherwise known as a ‘French sixth’: Christopher Gibbs (2000, p. 105) says of this ending: “within the last movement of the quintet, darker forces continue to lurk: the piece ends with a manic coda building to a dissonant fortissimo chord with a D-flat trill in both cellos, and then a final tonic inflected by a D-flat appoggiatura… The effect is overwhelmingly powerful.”[4], There are similarities here with the ambivalent ending of Richard Strauss’s tone poem Also Sprach Zarathustra. Thus, the alt chord is equivalent to the tritone substitution with a sharp–eleventh alteration. So instead of G7 –> C, it will be “tritone sub” –> C . If you’re still wondering how we got Db as an augmented fourth interval below G, then you need to subscribe to our early bird list to know when we’re releasing our latest comprehensive workbook on … The tritone substitute dominant often contains the original dominant pitch (the sharp fourth, also called sharp eleventh or flat fifth, relative to the original root) due to its importance melodically and tonally, and this is one of the ways in which substitute dominants may sound and function somewhat differently than conventional dominant chords. This always confused me. "A Royal Scam: The Abstruse and Ironic Bop-Rock Harmony of Steely Dan", Satyendra, Ramon. First, this involves three trig functions, tangent, sine, and secant.

How are tritones used to substitute dominant chords in chord progressions? This is a way of substituting V7 chords. Though examples of the tritone substitution, known in the classical world as an augmented sixth chord, can be found extensively in classical music since the Renaissance period,[1] they were not heard until much later in jazz by musicians such as Dizzy Gillespie and Charlie Parker in the 1940s,[2] as well as Duke Ellington, Art Tatum, Coleman Hawkins, Roy Eldridge and Benny Goodman.[3]. Jerry Coker explains: Tritone substitutions and altered dominants are nearly identical... Good improvisers will liberally sprinkle their solos with both devices. ... the distinction between the two [tri-tone substitution and altered dominant] is usually a moot point.[11]. Tritone substitution is when a dominant 7 chord is substituted for the dominant 7th chord a tritone away. In the case of D♭7 to Cmaj7, the implied scale behind D♭7 would be D♭, E♭, F, G, A♭, B♭, C♭. Classical harmonic theory would notate the substitution as an augmented sixth chord on ♭II (the augmented sixth being enharmonic to the dominant/minor seventh). The rules behind “tritone substitution” say that you can replace this G dominant7 with the dominant chord that is 3 whole steps away (or a “tritone” away). This site uses Akismet to reduce spam. This also reinforces the downward movement of the thirds and sevenths of the chords in the progression (in this case, F/C to F/C♭ to E/B). Example: G7 is replaced by Db7.

"[6] Patricia Julien says it involves replacing "harmonic root movement of a fifth with stepwise root movements (e.g., G7–C becomes D♭7–C) so that although stepwise root movement is involved, the relationship between the chords is functional".[8]. So a G7 would become a D♭7 (the root note is a tritone away). However, in 31 equal temperament and other systems that distinguish between 7:5 and 10:7, tritone substitution becomes more complex.
