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.
