Music Theory From Nothing

Twenty short lessons that build music theory from nothing. Every one of them has something you press: count the half steps yourself, play the chord, hear the scale change. Lessons 15 to 17 are yours to build in, and what comes out is a song you wrote.

How this works

The order below is the one that costs you the least effort, because each lesson leans on the one before it. That is a suggestion, not a gate.

Nothing is locked. If you already know what a chord is and came here for keys, open lesson nine and ignore the rest. This page remembers which lessons you opened, so you can always find your way back to where you stopped.

The twenty come in seven blocks. Each block finishes a subject before the next one starts, so you can stop at the end of any of them and still have something whole.

Lessons 15 to 17 are different. Instead of following steps you pick your own chords, your own groove and your own tune, and you keep what comes out. They work on their own too: land on one of them cold and it hands you something to start from.

After the twenty

You will not be finished, and that is the good news. What you will have is enough to read any other page here without being sent back for a definition.

The obvious next step is seventh chords, which is what happens when you keep stacking. After that the knowledge base opens up: modes, jazz harmony, production. And the exercises are where it stops being knowledge and becomes something you can actually do.
