Extensions can be added at your own will 🙂 We will only cover triads and seventh chords here.

Let's see how many tertian chords are in the Harmonic Minor Scale, starting on each of its scale degrees. These thirds can be either major (interval of 4 semitones) or minor (interval of 3 semitones). Tertian chords are built by stacking thirds. Starting with the tertian Chords of the Harmonic Minor Scale Let's get into building chords with tertian harmony! The modes are a very useful tool for building chords since each mode presents a scale degree as a “tonic,” making it easy to see the potential tertian and non-tertian chords. Reordering the scale degrees of our parent Harmonic Minor Scale yields these modes. The modes of the Harmonic Minor Scale are as follows: A mode's scale degrees are in reference to its new starting point.

So the first mode of the Harmonic Minor Scale is built on the first note (therefore it's the same), and the second mode of the scale is built on the second note, and so on so forth. Before we get into chords, let's quickly go over the Harmonic Minor modes.Įach mode is built starting on a different scale degree of the Scale itself.
