Describe what you're going for. Sonorus builds the harmony. You shape it into a song.
Free during beta
From your first idea to a full arrangement. Sonorus handles the music theory so you can focus on the music.
Type a mood, genre, or vibe. Sonorus generates a musically coherent chord progression grounded in real harmony and voice-leading rules.
Natural-language editing powered by AI. Describe the change you want and Sonorus modifies your chords while keeping the rest of your progression intact.
A chord palette that knows music theory. Chords are grouped by harmonic function and colored by tension. Switch between guitar tabs and piano diagrams instantly.
Play back any section or your entire arrangement with live chord highlighting. Export as MIDI - sections, repeats, and all - and open it straight in Ableton, Logic, or wherever you work.
Add Verses, Choruses, Bridges, Intros, Outros - each with their own chords, key, and repeat count. Arrange them into a full song, not just a single loop.
No theory degree required.
Name it, set the vibe, and describe your first section. Sonorus handles the rest.
One click generates a full chord progression matched to your mood, genre, and section type.
Swap chords from the color-coded picker, ask the AI to "make it darker", duplicate sections, transpose keys. Jot down lyrics right in the canvas while the harmony is fresh.
When it sounds right, export. Your full multi-section arrangement becomes a single MIDI file ready for any DAW.
Type a vibe. Get chords that make musical sense.
Every chord Sonorus generates follows voice-leading rules and harmonic function. The output sounds like music because it's built on how music actually works.
Verse. Chorus. Bridge. Intro. Outro. Each section has its own chords, key, and repeat count. You're building an arrangement, not generating a 4-bar clip.
AI assists, you decide. Swap any chord from the picker. Edit with a prompt. Transpose the whole song. Sonorus never takes the wheel. It hands you better options.

Full staff notation alongside chord diagrams. Read it the way you were taught.
Full tab notation for every chord in your progression.
Choose your playback sound: piano, guitar, synth, and more.
One prompt generates your entire arrangement. Every section, all at once.
Nope. Sonorus handles key selection, chord voicing, and harmonic function for you. Just describe what you want - "sad verse", "upbeat chorus" - and it figures out the theory. That said, if you do know theory, the chord picker gives you full control over every harmonic choice.
All of them. The export is a standard MIDI file. Ableton Live, Logic Pro, FL Studio, GarageBand, Reaper, Pro Tools, Cubase - if it reads MIDI, it works.
Yes. Sonorus is free during beta. Just open it and start writing.
Most AI music tools generate audio clips you can't edit. Sonorus generates chord progressions - structured, editable, exportable as MIDI. You keep full control over every note, and you finish the production in your own DAW with your own sounds.
Absolutely - that's the point. Use the AI to describe changes ("make the bridge darker"), swap chords manually from the harmonic picker, or do both. Every chord in every section is fully editable.
Yes. Each section has a lyrics panel so your words and chords live in the same place. Write while the harmony is fresh, then export the whole thing when you're ready.
