Active Tones and Restive Tones are the foundation of Western Harmony. If you haven’t seen it already, I really recommend watching a previous video I made about resolution:

This topic relates to it very well.

A long time ago before there was tonality, notes would meander around and there were some pretty melodies but you didn’t have notes with different power than others. All notes were essentially equal.

The best way to demonstrate the power behind tonality is to play a major scale and stop on the 7th note. Go to your piano and try this, you will find that you simply can’t stop – it might drive you crazy – but you will need to resolve and hit that last note. Modal music was much different because there were no raised leading tones – which meant you didn’t really need to resolve.

So getting back to the question, what are the Restive Tones? They are the 1, 3, and 5 notes in your respective key. If you play the other notes in the key you will find that they need to be resolved to either the 1, 3, or 5.

So what are the Active Tones? These are the other notes in your key besides the 1, 3, and 5. They are the notes that when played must be resolved to one of the restive tones.

In some ways, this is a simple subject with complex implications. Make sure to check out my other videos – specifically the one on resolution – to learn more.
