Advanced Bass: Diminished II V Substitution

A cool harmonic concept that bebop players have used for years is substituting dominant 7th chords – built in minor 3rds – over the V7 chord of the key. In this lesson, we’ll cover this concept to learn the possibilities of Diminished II V chord substitution over the II V I progression.

I could be wrong, but shouldn’t the article say “substituting DIMINISHED 7th chords over the V7”?

Hi Dave

No, you are incorrect. What we are doing is substituting Dominant 7th chords that are built in minor 3rds. However, if you move the root of each one of these Dom7th chords up a minor 2nd, you’ll end up with four Diminished 7th chords- but that’s the topic of another lesson.
