Theory for producers who learn by doing.
Melogine teaches music theory through a piano roll — the way you already think about music.
No sheet music. No treble clef. F*** sheet music — just the piano roll you already think in.
Available on iOS 18.2 and above
You can feel when a chord progression is right. You just don't know why yet.
Most music theory resources were built for classically trained musicians. Melogine was built for producers who work in DAWs, think in piano rolls, and learn by experimenting — not reading.
Sandbox
Build chords by feel. Understand them by theory.
The Ghost Engine guides you note by note — showing which scale degrees and chord tones fit your progression in real time. No lectures. No staff notation. Just the next right note, when you need it.
Fundamentals
Theory that finally makes sense in a DAW.
Intervals, scales, chord construction — all taught through the piano roll you already know. No treble clef. No sheet music. Just the concepts that make your productions better.
Challenges
Test what you know. Build what you don't.
Ear training, chord recognition, voice leading, modal interchange — progressive challenges that meet you where you are and push you further every session.
Glossary
Look it up without losing your flow.
Intervals, chord symbols, and core terms — explained in plain language and tied to the piano roll, so you can clear up confusion mid-session instead of tab-hunting on Google.
Emotional Fingerprint
Know the feeling before you finish the chord.
A real-time radar chart maps the emotional character of your progression across eight axes — Joy, Tension, Melancholy, Longing, and more. Watch it shift as you build.
