Scale Degree

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.
