Diatonic Triads and Four-Part Voicing Microlesson

Introduction to Diatonic Triads and Four-Part Voicing

This section will review diatonic triads; and the beginnings of four-part voicing, specifically voice parts, vocal ranges, open and closed chord positions, and chordal movement.

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 the 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 3^rd scale degree; but when descending, the 3^rd, 6^th, and 7^th degrees are lowered, which is technically using the Natural Minor Scale.
