Understand the music you hear. Learn notes, scales, chords, keys and rhythm through short, interactive lessons with no sheet music or experience required.
Learn music theory by ear, with a piano built into every lesson.
Music theory finally makes sense. Detune teaches you how music works through short, interactive lessons and ear-training exercises. Learn with a piano built right into your phone. No instrument, sheet music or previous experience required.
LEARN MUSIC THEORY BY EAR
Most music theory apps start with abstract rules. Detune starts with sound. Hear the difference between notes, intervals, chords, scales and rhythms, then learn the name and the idea behind what you heard. Every concept connects back to the music you already know and love, so it sticks.
A CLEAR PATH FROM ZERO
Follow a structured course through the foundations of music:
Notes and pitch
Major and minor scales
Chords and chord progressions
Intervals, fifths and octaves
Keys and tonality
Melody and musical phrases
Rhythm and timing
Each unit builds on the last, so you always know what to learn next and why it matters.
SHORT, INTERACTIVE LESSONS
No long videos. No dense textbooks. Every lesson gives you something to hear, play or answer, so you understand one idea at a time and practise it straight away. Lessons take just a few minutes, which makes them easy to fit into a commute, a lunch break or the gap before bed.
TRAIN YOUR EAR
Ear training is built into the course, not bolted on. Recognise intervals, tell major from minor, follow chord progressions and pick out rhythms. Over time you'll start hearing how your favourite songs are put together.
A PIANO IN YOUR POCKET
Use the built-in piano throughout every lesson. You don't need to own an instrument. If you already play piano, guitar, bass or sing, Detune helps you understand what you're playing and hearing, and fills the gaps that learning by ear or from tabs leaves behind.
