Increase Tension by Using Dominant Diminished!

Dominant chords are fairly flexible in terms of soloing. You can use the mixolydian scale, the altered scale, the whole tone scale, and more. And with alterations, like #9, b9, #11, and b13 chords, there are always a ton of options that you can use to add color and tension to your lines. Honestly, you can play pretty well anything over a dominant chord, so long as you focus on the resolution it’s making back to the tonic chord.


Today, we’re going to specifically check out the half-whole diminished scale. This is one of those techniques that, when used properly, can give a more sophisticated sound to your playing.

Building the half-whole diminished scale

Getting started, let’s look at how this scale is built. The half-whole diminished scale is an octatonic scale—meaning that there are eight notes in the scale, instead of the usual seven and sometimes five or six. As the name implies, we’ll build this scale with consecutive half and whole steps, repeating up the scale until we return to the tonic. This is distinct from the whole-half scale, which is built similarly, but with repeating whole and half steps.


The structure of the scale makes it totally symmetrical, which makes it nice when it comes to filling out a whole measure.


Interestingly, much like other symmetrical scales, there are also only three distinct transpositions of this scale, and the rest are technically inversions of previous versions.


Take a look at C half-whole diminished:

Finally, let’s look at D half-whole diminished:

Now you’ll realize as we come to Eb half-whole diminished, we’re actually repeating the same notes as we did in C half-whole diminished—it’s just an inversion of the scale. The same goes for E and C, F and D, and so on.
