Tip #184 – Unique Use of Dominant 13 (b9 #11) Chord

Some jazz performers, arrangers, and composers have the inclination to add tension tones and various extensions on top of simple triad chord harmonies. Not that it is a bad thing, but it can become mundane if used too often or too frivolously.

With that out of the way, one chord that I have noticed some people using is the dominant 13 chord with alterations of a b9 and #11. Usually, this is recognized as a V 13(b9 #11) in the jazz tune – but here is another use of it:

Let’s first start by separating the dominant 7 from the upper extensions. That gives us the V7 chord and the (b9 #11 13) above.

If we reharmonize the (b9 #11 13) be their enharmonic, we get a minor triad a tritone above the root of the chord.

Typically, there is no major or natural minor key that has both a V7 and bii. However, who said that the dominant chord has to function as a V7 chord? Instead, we can think of it as a tritone substation making it a bII7 in a minor key with the minor triad acting as a v. In which case, both the bII7 and v chords resolve to the minor tonic triad of i.

Try it out for yourself!
