Chord Progression Generator

This musical composition tool assists songwriters, producers, and students by generating harmonically sound chord progressions based on music theory principles. Users select a root key (e.g., C, F#, Bb) and scale type (Major or Minor), and the algorithm constructs sequences using Roman Numeral Analysis to ensure chords sound good together.

The generator draws from a library of established progression templates used in popular music genres including Pop (I-V-vi-IV), Jazz (ii-V-I), Blues (12-bar structures), and emotional ballads. It instantly transposes these abstract formulas into specific chords for the selected key, displaying both the chord names (e.g., C Major, A Minor) and their diatonic function (I, vi). This helps musicians break out of repetitive habits and explore new harmonic territories without needing deep theoretical knowledge.

Common applications include overcoming writer's block, finding backing tracks for improvisation practice, learning how different emotions are conveyed through harmony (e.g., using 'vi' chords for sadness), or quickly sketching out proper accompaniment for melodies. The tool operates client-side, allowing instant experimentation with different keys and moods useful for both beginners learning their first songs and pros developing complex arrangements.
