## Description

Learn music theory by playing !

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.

Free to learn. No ads.
