Clef - Music Theory

Three daily quests to collect, and your rewards flying up into your counters. A rebuilt light theme, and a microphone that finally holds the note.

Clef turns music theory into a game. Short lessons, sound in every exercise, and a leaderboard that makes you want to come back tomorrow.

• REAL SHEET MUSIC READING Not just quizzes: learn to read real sheet music in treble and bass clef — rhythm, scales, harmony and more. Sixteen chapters, three years of curriculum.

• HEAR WHAT YOU LEARN Every idea is played, not just read. A sharp raises a note by a half step — and you hear it. A third, a fifth, a scale you build note by note: your ear learns alongside your eyes.

• TRAIN YOUR EAR Intervals, chords, cadences, perfect pitch — recognize music by ear, with a real audio engine and melodies recorded on real instruments.

• SING IN TUNE Use your microphone to practice pitch-matching, with real-time feedback note by note.

• PLAY AGAINST OTHERS A live weekly league, clubs, and your school ranked against other schools. Join yours with a code.

• COME BACK EVERY DAY Three daily quests to collect, a daily goal, a streak to keep alive. Plus spaced review that brings old lessons back exactly when they start to fade.

• PICK YOUR INSTRUMENT Piano, guitar, violin, trumpet, voice… Clef adapts sounds and exercises to your instrument.

• English and French, letter names (C D E) or solfège (Do Re Mi) — whichever you prefer.
