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.

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.
