Introduction to Secondary Dominants and Secondary Leading Tones

This section will discuss secondary dominants and secondary leading tones. These are chords that provide a colorful harmony of tension and release. This easily occurs from using a chord, outside of the original key, and then resolving back to a chord within the original key.

Lesson Key Terms:

  • Natural Minor Scales: This scale uses the same tonic as the major scale. To create a natural minor scale, use lowered third; lowered sixth; and lowered seventh degrees from the major scale.
  • Harmonic Minor Scale: The harmonic minor scale has two lowered scale degrees, the 3rd degree and 6th degree. Using the major scale as a foundation, lower the 3rd and 6th degrees of the major scale. The result is the Harmonic Minor Scale.
  • Melodic Minor Scale: This is the most unusual minor scale because it has distinct parts for ascending and descending. When ascending, the Melodic Minor Scale only lowers the 3rd scale degree; but when descending, the 3rd, 6th, and 7th degrees are lowered, which is technically using the Natural Minor Scale.

CORRECTION: At 1:08 in the video, in the second sentence after the semi-colon on the slide: Should read the following: “The second, third, and sixth-degree triads are minor.”

Clarifications:

  • You can only tonicize a major or minor chord- you wouldn’t be able to tonicize a vii° chord because it is diminished.

  • You can’t tonicize an I chord.

  • You can’t have a V/IV in a major key because there wouldn’t be a foreign tone. It must be a V7/IV to work.
