Chords, melodies and basslines
in seconds, not hours
Progrese is an online chord progression generator for musicians, producers and beatmakers. Pick a key and mood — and the tool builds a musically coherent progression with melody, bassline and arpeggio. Play it right in your browser, or download everything as MIDI for your DAW.
Why Progrese
Everything you need to kick off a song
No writer's block, no theory rabbit holes — just a key, a mood, and a ready foundation for your next track.
Always musically correct
Every chord is strictly diatonic to the chosen key and scale — so the progression never sounds off, whatever combination you pick.
8 thoughtfully designed moods
Happy, sad, dreamy, epic, chill/lo-fi, dark, romantic and nostalgic — each with its own key mode, tempo and set of typical progressions.
Melody, bass and arpeggio
Melody, bassline and arpeggio are generated automatically from the chord tones, so they always sit in tune with each other.
Instant playback
Play the whole progression, or just one layer, right in your browser — no plugins, nothing to install, works on mobile too.
MIDI export for your DAW
A standard .mid file with 4 tracks (chords, melody, bass, arp) that opens in Ableton, FL Studio, Logic, Reaper and Cubase.
Free, no limits
No sign-up, no cap on exports. Anything you generate and download is yours — including for commercial use.
Workflow
How it works
Four steps between a blank page and a finished foundation for your song.
Pick a key and a mood
The key sets the root note; the mood decides major or minor, the tempo, and the overall character of the progression.
The tool builds the chords
The progression is built solely from chords diatonic to the chosen key — no stray or random notes, always a consistent sound.
Melody, bass and arp are added
Pick a specific style for each layer, or leave it on "auto" and get a different variation every time.
Play it, or export it
Loop it right in your browser, or download the MIDI file and keep going in your DAW — no license restrictions attached.
Moods
Eight moods, eight different characters
Try the same key across every mood and hear how much it changes the character of a song.
Happy
Bright pop progressions, open and energetic.
Sad
Melodic melancholy, slower tempo.
Dreamy
Floating seventh chords, slow and soft.
Epic
Dramatic, cinematic character.
Chill / Lo-fi
Relaxed groove, great for beats.
Dark
Mysterious, tense chord jumps.
Romantic
Full, warm sound, slow tempo.
Nostalgic
Wistful pull between the vi and IV chords.
