## Description

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.

What's covered
Scale degrees · major and natural minor scales · pentatonics · intervals · key signatures and relative minors · the circle of fifths · diatonic triads · seventh chords · suspended chords · chord formulas · chord progressions · the seven modes

Roman numerals and Nashville numbers throughout.

Built to respect you
No account. No ads. No tracking. Your progress syncs privately through your own iCloud — we can't see it, and there's nothing to sign up for.
