I was asked a couple of weeks ago what are some of my favorite scales. The A harmonic minor scale would be at the top of that list. It is a fun scale to use to build technique, improvise and compose with. Of the four scales commonly used in Western music (major, melodic, harmonic, and natural) it is unique because of the large step (augmented second) between the 6th and 7th note of the scale.
In this video I demonstrate the scale as well as play a couple of improvisations with the scale.
