Klef: Learn Music & Theory

Klef is the pocket conservatory that makes learning music as fun as a game. Start from zero or level up — from reading notes to ear training, chords to music theory, it's all in one app.

WHAT YOU'LL LEARN
• Sight Reading — read the staff fast, on reflex (treble/bass/mixed clef)
• Ear Training — hear and name intervals, chords and melodies
• Rhythm — feel the beat and note values
• Music Theory — scales, modes, chords and key signatures

TOOLS — ALL IN YOUR POCKET
• Tuner — guitar, bass, ukulele, violin; tap a string to hear its tone
• Metronome — time signatures, subdivisions, gradual tempo, tap tempo
• Chord Lab — identify chords, find chords, scales, circle of fifths, progressions
• Interactive piano, guitar and bass

WHY KLEF
• Real progress in 5 minutes a day
• Streaks, daily rewards and a weekly league keep you going
• Duel a friend and climb the ranks
• Every tool teaches the "why" and "how," not just the answer

Whether your instrument is piano or guitar, Klef turns you into a musician who reads notes and trains the ear.
