Lesson 138: Mediant and Submediant Chords
The mediant chord of a given chord is a chord on the third scale degree. That means that the mediant chord of a C chord can be
The submediant chord of a given chord is a chord on the sixth scale degree. That means that the submediant chord of a C chord can be
Using Mediant and Submediant Chords
Mediant and submediant chords have many common tones with the original chord. The idea is that you replace the original chord with a mediant or a submediant chord.
The cadence F - G7 - C which is very common in classical music has become Dm7 - G7 - Cmaj7 in jazz ( Dm7 is the submediant chord of F)
Mediant and submediant chords are often used in deceptive cadences, for example:
Below you can see a nice ending to Fly Me to the Moon by Bart Howard, using a deceptive cadence. The final melody note is c, so you can change the cadence Dm7 - G7 - C to Dm7 - G7 - Abmaj7 ( a submediant chord).
Examples from My Composition Blue Tango
The B section of my composition Blue Tango has the following changes:
Fmaj7 - Fmaj7#11 - Em7 ( Fmaj7 is the mediant chord of Dm7 and Em7 is the mediant chord of Cmaj7, so this can be looked at as a reharmonization of Dm7 - Dm6 - Cmaj7, which in turn is a reharmonization of Dm7 - G7 - Cmaj7)
Gm7 - Gm6 - Fmaj7#11/A ( Fmaj7#11/A, if looked at as an Am chord, is the mediant chord of Fmaj7, so this can be looked at as a reharmonization of Gm7 - Gm6 - Fmaj7, which in turn is a reharmonization of Gm7 - C7 - Fmaj7)
