Jazz Piano Chords: II-V Progression

Jazz-Piano-ChordsAs our fun with jazz piano chords continues, here we will make reference to a previous lesson that focused on turning a minor 7th chord into a minor 9th chord. Specifically, we will use the same Dmin9 chord voicing for our purpose. You will see that lesson here.

From that position, we can easily progress to a V chord, using a very tasteful voicing… and it’s “easy as pie” to achieve this!

Simply play that Dmin9 voicing and then take that 7 of the chord (in this case, the C) and lower it one half step. The resulting voicing combination looks like this:

Jazz-Piano-ChordsThese are two of the most popularly played jazz piano chords of all time. Again, it’s that one little “switch” that turns the Dmin9 into a G13 chord.

Let’s just back up a little and look at a basic G7 chord here:

G  B  D  F

If we relate this chord to its corresponding Mixolydian scale, we see that it consists of the 1, 3, 5, and 7 of this scale:

G  A  B  C  D  E  F  G  A  B  C  D  E
1   2  3   4  5   6  7  8   9……………. 13

Extending the scale beyond an octave shows that the 13 is the same as the 6. When we play dominant 7th chords, we refer to that 6 as the 13. Hence, our symbol for this chord is G13.

What we are playing is a II-V chord progression. This works great as a left hand chord voicing combination when playing with a bass player since he or she will be playing the root of the chord. However, if you are playing cocktail piano, you are performing as a soloist. Often, you will want to compliment these chord voicings by either preceding them or following them with their corresponding roots ( in other words, Root > Voicing > Root > Voicing or Voicing > Root > Voicing Root)

Is it necessary to always accompany these voicings with their corresponding roots? Not really. Actually, often is the case when a jazz pianist, even when playing solo, will simply play the voicings with the left hand while playing the melody or improvising with the right hand. It’s interesting because this actually sounds good when you do so. You see, it’s the nature of that 3 and 7 of each chord that really defines each of them. Adding the roots certainly adds significant “bottom” or substance to these chords.

By all means, explore these two popular jazz piano voicings in other keys. You’re on your way toward chord mastery!
