Theory

In Chapter 3.5 Major and minor third you’ve learned about major and minor thirds . In Chapter 3.6 Perfect fifth you’ve learned what a perfect fifth is. In this chapter, you will learn that there are two kinds of triads, namely the major triad and the minor triad. In the videos and examples I show how to make major and minor triads. You learn to recognize major and minor triads and you are going to make them yourself in the exercises. You will also learn to distinguish major and minor triads by ear.

1. What are major and minor triads?

When you play triads on the piano, you can see that the distance between the tones of the different kinds of triads is not always the same. For example, the triad C E G is comprised of the major third C E and the perfect fifth C G.

major triad
The triad C E G is comprised of a major third and a perfect fifth.

But, this isn’t the case with all of the triads. For example, the triad D F A is comprised of the minor third D F and the perfect fifth D A.

minor triad
The triad D F A is comprised of a minor third and a perfect fifth.

The triad with a major third and a perfect fifth is called a major triad.
The triad with a minor third and a perfect fifth is called a minor triad.
Also by ear, you can hear a difference between a major triad and a minor triad.
