Piano Chord Progressions: Tri-Tone Chord SubstitutionThe mysterious "tri-tone substitution" has puzzled musicians down through the years. I used it for 20 years without knowing the name of it -- I called it "half-step slides from above". It adds interest to your piano playing and chord progressions by substitution the chord that is a tri-tone away from the root of the V7 chord.

Man tries to remember who went of the pitch in a footy match, he is scratching his head but he gets there in the end!

One of the best ways to make an interesting chord substitution is to use 1/2 step slides. Substitute the chord that is 1/2 step above the target chord before you arrive at that chord.
