Chord Progression Generator

Endless chord ideas for your next song.

Chord Progression Generator writes chord progressions that sound right: choose a key, a mode and a style, tap Generate, keep the chords you love and regenerate the rest. Every chord shows its name, its Roman numeral and its harmonic function. Every feature is free.

GENERATE BY STYLE
• Pop, Rock, Jazz, Blues, Soul / R&B, Folk, Classical, Cinematic and Lo-fi.
• Major, natural and harmonic minor, Dorian, Mixolydian, Lydian and Phrygian.
• 4 or 8 chords; triads, seventh chords or extended chords (9, 11, 13).
• A real harmonic grammar for each style, not random lists: tonic, subdominant and dominant functions, a proper cadence at the end, no chord repeated twice in a row.
• Applied dominants and tritone substitutions where the style uses them, borrowed chords where they sound good.

LOCK & REROLL
• Lock any chord with the padlock and generate again: only the others change, and they still lead into the locked ones.
• Undo any change.

EDIT WITH SMART ALTERNATIVES
• Tap a chord to hear it and see what else fits: chords with the same function, the dominant of the next chord, tritone substitution, chords borrowed from a parallel mode, other colours (sus, add9, sevenths…).
• “Why it works”: every chord change explained – authentic, plagal, deceptive and half cadences, circle of fifths, borrowed colour, common notes.

LISTEN
• Sampled grand piano, strings pad or guitar.
• Voicings with smooth voice leading: the notes move as little as possible from chord to chord.
• Block chords, pulse, arpeggio or strum; tempo 50–180; loop; 1 or 2 bars per chord, two per bar or a fast turnaround.
• Sample-accurate timing from the audio engine.

WRITE THE WHOLE SONG
• Verse, pre-chorus, chorus, bridge, intro and outro, each with its own progression, played in order.
• Change the key and every chord follows; change the mode and each chord keeps its degree.

LIBRARY OF CLASSIC PROGRESSIONS
• Four-chord pop loop, 1950s progression, ii–V–I, 12-bar blues, Andalusian cadence, jazz turnaround, backdoor ii–V, Mixolydian vamp and more, written in Roman numerals and loaded in your key.

DIAGRAMS, SAVE AND EXPORT
• Chord diagrams for guitar (with capo and left-handed view), ukulele and piano.
• Save your ideas as projects.
• Export MIDI (chords and bass on separate tracks, chord names as markers) for any DAW.
• Share as text with chord names and Roman numerals, or as ChordPro.
