Secondary Dominant Chords In Jazz Piano
In this 5 minute masterclass we’re going talk about the second scale degree dominant, the 5 of 5, and it’s different functions. I wanted to do a short masterclass about this topic just because this very common harmonic movement keeps coming up in almost all the other courses, and I want to make sure everyone understands what it means.
The Secondary Dominant Chord Progression
In the key of C, we have the dominant G7 to Cmaj. The 5 of 5 is simply a dominant to that 5 chord, so D7 going to G7, resolving to Cmaj7. (Notice also that it is still a 2-5-1, even if the D is a dominant chord instead of a minor Chord)
Descending b3 Diminished Progression
We will look at the function of the descending b3 diminished chord in a situation like Em7 – Ebdim7 – Dm7 – G7 and discover how it relates to a secondary dominant. At first glance, the Ebdim7 doesn’t appear to have a clear dominant function to the Dm7 but, looking closer, the Ebdim7 has close ties to D7, the secondary dominant in this progression.
Tune Examples and Improvisation
Secondary dominants are used often in jazz standards and we will look at some examples including "Take the A Train", "But Not For Me" and "Smoke Gets In Your Eyes". Approaches to improvisation are also discussed including various possible substitutions and re-harmonisations.
