Theory

In Chapter 2.7 Sixth, seventh and octave you’ve learned what a seventh is. In this chapter, you will learn that there are two kinds of sevenths, namely the major seventh and the minor seventh. In the videos and examples I show how to make major and minor sevenths. You learn to recognize major and minor sevenths and you are going to make them yourself in the exercises. You will also learn to distinguish major and minor sevenths by ear.


1. What are major and minor sevenths?

When you play sevenths on the piano, you can see that the distance between the tones of the different kinds of sevenths is not always the same. For example, the seventh C B is made up of eleven half steps (five whole steps and one half step), or a half step below the octave.

major seventh
The seventh C B is a half step below the octave C C.

But, this isn’t the case with all of the sevenths. For example, the seventh D C is made up of ten half steps (five whole steps), or a whole step below the octave.

minor seventh
The seventh D C is a whole step below the octave D D.

The seventh C B is greater than the seventh D C.
The seventh C B is called a major seventh and the seventh D C is called a minor seventh.
Also by ear, you can hear a difference between a major seventh and a minor seventh.
