The map

See why notes fit.

Theory starts as a picture, not a list to memorize. Seven notes are inside the key — they fit. The rest are outside. Spot the one that doesn't belong.

Turn a scale into chords.

A chord is just a starting number plus every-other note. Pick any degree — take it, skip one, take the next, skip one. Same rule, new starting point, every time.

The cheat code

One pattern. Every key.

Names change. The pattern does not. The Roman numerals and the major/minor shape stay locked — only the chord names slide. Learn it once, play it in all twelve.

Key of C major
Start simple. Go deep.

Four plain chords. Then make them yours.

The same progression carries jazz, gospel, and neo-soul once you know the moves. Tap one — hear the color change and read why it works.

Start with C → F → G → C, then add a move.
