Mediant: Chords & Harmonize

by Songdeed

$4.99 · Designed for iPad. Not verified for macOS.

Pick a key, tap Generate, and get musically sound chord progressions — diatonic to lush chromatic. Harmonize any melody. Export MIDI or MusicXML to your DAW. Chord progressions, on tap. Mediant writes musically sound chord progressions. Pick a key and mode, tap Generate, and get functional progressions — real tonic / subdominant / dominant motion and proper cadences — that you can audition, reorder, and drop straight into your DAW. HOW IT WORKS • Pick a key, mode, length, and voicing, then tap Generate. Mediant offers several progressions, ranked best first — tap Regenerate to cycle them. • Two dials shape the mood: Brightness (major ↔ modal) and Tension — from plain diatonic triads up through 7ths, secondary dominants, borrowed chords, mode mixture, and tritone subs. • Tap any chord to swap it from a full palette, or move, duplicate, and delete. Build a whole progression by hand if you like. • Harmonize a melody: draw one on the grid or import a MIDI or MusicXML file, and Mediant writes the chords underneath it. WHAT'S INSIDE • Producer-friendly voicings — spread pads, close, open, and drop-2 — with smooth voice-leading between chords. • A live chord-symbol notation preview on a staff. • MIDI and MusicXML export — for your DAW, or MuseScore, Sibelius, Dorico, and Finale. • Fully offline. No account, no sign-in, no ads, no in-app purchases. • Private by design — Mediant collects nothing. Your music never leaves your device unless you export it. Mediant is by Songdeed.
