"[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]. A Tritone is the 5th tone of a scale minus one 1/2 step. Years ago you could get banned from the church for even playing a tritone due to its very “harsh” or dissonant sound. For example, in the progression Dm7–G7–CM7, substituting D♭7 for G7 produces the downward movement of D–D♭–C in the roots of the chords, typically played by the bass. A tritone substitution is the substitution of a dominant seventh chord with another chord whose root is a tritone (augmented fourth) lower.

Or in G major it would be between C and F sharp: First, this involves three trig functions, tangent, sine, and secant. One of the most common tritone subs is Tritone Sub of V. Thus, the alt chord is equivalent to the tritone substitution with a sharp–eleventh alteration. Here in Part 2 of our discussion on tritone substitution we will go through some specific examples of how tritone substitution works in practice and discuss some ideas for improvisation. One of the most common Chord Substitutions in Jazz is the Tritone Substitution. Example: G7 is replaced by Db7.

Their initial letters, t, s, and s, are the same letters as the initial letters of the name of this technique, t rigonometric s ubstitution.

And my own trick for substituting them on the fly: replace the dominant 7 chord by a II-V starting 1 semitone up. The Tritone substitution is a very powerful way to add some extra tension and color to a II V I cadence. The harmonic seventh chord (approximating 4:5:6:7) contains a small tritone, so its substitution must contain a large tritone and therefore will be a different (and more dissonant) chord type.[15].
