Let us now take a look at the other degrees. We will start with the II and VII degrees.

The II degree or supertonic has a subdominant function. It can be used as a substitute for the IV degree.

The VII degree or leading tone has a dominant function. It can be used as a substitute for the V degree.

In the next example, you can alternate between chords using the buttons and listen to the different harmonizations:

Change IV degree to II degree Change V degree to VII degree
