Scale Degree

New: choose your own curriculum. Pick a focused core or the full syllabus across every topic and key — and change your mind any time without losing progress.

Know your keys cold.

Scale Degree turns music theory into something you can recall under pressure — not facts you looked up once, but fluency you keep. A few minutes a day, one key at a time.

Practice that adapts Every question is scheduled by spaced repetition, so you see what you're about to forget and skip what you already know. Difficulty ramps inside a lesson and backs off when you're struggling. Sessions stay short on purpose.

Teaches, then tests Each topic opens with a plain-language explanation and a worked example. Theory terms inside questions are tappable — blank on "leading tone" mid-question and the definition is one tap away, without losing your place.

Earn your keys Start in C. Master a key and the next one opens. Choose how far you want to go: a focused core, or the full curriculum across every topic and key.
