Tritone Substitution
A precise tool.
What is the Tritone Substitution & How does it work?
Tritone substitution is a technique in music theory where a chord is replaced by another chord that is a tritone (three whole steps) away from the original. This substitution can add harmonic interest and complexity to a piece of music.
The formula for finding the tritone substitute of a dominant seventh chord (V7) in a given key is straightforward. If you have a V7 chord, its tritone substitute will be a VII(sharp)7 chord.
VII(sharp)7 = V7 + text{tritone}
V7 = dominant seventh chord, VII(sharp)7 = tritone substitute chord

Frequently Asked Questions
What is tritone substitution in music?
Tritone substitution is a technique where a dominant seventh chord (V7) is replaced by another chord that is a tritone away, adding harmonic interest.
How do you find the tritone substitute of V7?
The tritone substitute of V7 is VII#7. You add a tritone to the original dominant seventh chord.
Can tritone substitution be used in any key?
Yes, tritone substitution can be applied in any musical key using the same formula.
What is the purpose of tritone substitution?
Tritone substitution adds harmonic complexity and interest to a piece of music by replacing dominant chords with their tritone equivalents.
Is tritone substitution common in all types of music?
While more prevalent in jazz, tritone substitution can be found in various genres of Western music.
Can tritone substitution be used with other chords besides V7?
Tritone substitution is primarily associated with dominant seventh chords (V7), but similar techniques can be applied to other chord types.
What is the difference between a dominant seventh and its tritone substitute?
A dominant seventh chord (V7) and its tritone substitute (VII#7) are three whole steps apart, creating a different harmonic tension and resolution.
