## What is Contrapunctus?

Give your melody a second voice.

Contrapunctus writes counterpoint. Draw a melody on a simple grid — or import a MIDI or MusicXML file — and it composes a genuinely independent second line against it: real first-species counterpoint, obeying the voice-leading rules right down to the cadence.

HOW IT WORKS
• Draw a melody on the timeline (leave a gap for a rest), import MIDI/MusicXML, or type it in.
• Contrapunctus generates a legal counter-line above or below, updating live.
• Cycle the distinct valid options — ranked best first — and pick the one your ear likes.
• Shape it with two dials: how strictly it favors sweet 3rds and 6ths, and how independently the voice moves.

WHAT'S INSIDE
• A real rule engine — no parallel fifths or octaves, proper cadences, and a musica-ficta toggle that raises the leading tone in modal keys.
• Works in every mode: major, dorian, aeolian and the rest.
• Live standard-notation preview of both voices.
• MIDI and MusicXML import and export — for MuseScore, Sibelius, Dorico, Finale, or your DAW.
• Fully offline. No account, no sign-in, no ads, no in-app purchases.
• Private by design — Contrapunctus collects nothing. Your music never leaves your phone unless you export it.
