Before we dive in, it is important to understand how this scale can be built. The harmonic minor scale stems from a need to have a leading tone in a minor scale that naturally doesn’t exist. In essence, the harmonic scale is a minor scale (Aeolian mode) with a raised 7th degree, in order to create a stronger resolution to the tonic. For that reason, sometimes you may see the harmonic scale referred to as being an Aeolian #7:
By raising the 7th degree, an augmented 2nd (with 1 ½ steps) is created between the 6th and 7th degree, which gives this scale a distinctive and exotic flavor.
As we did before, the same procedure is applied in order to get the modes from the harmonic scale; which is to change the root by inverting the scale and using the same exact notes of that particular scale. Again, each mode will have a different modal feel and, in the table below, you will see how each mode is built and their respective names:A Aeolian #7 A Locrian #6 A Ionian #5
Again, you should develop the knowledge of modes and the sensibility to how each sound so that according to each musical context you decide when and how to use it.
