About Chord Progressions
Chord progressions are sequences of chords played in a specific order that form the harmonic backbone of a song. Different genres have developed characteristic progressions that define their sound — from the catchy I-V-vi-IV pop progression to the sophisticated ii-V-I jazz pattern.
How This Generator Works
Select a key, mode, and genre to generate a chord progression. The generator displays both the actual chord names (e.g., C, Dm, Em) and the roman numeral analysis (e.g., I, ii, iii). Each chord card shows the chord quality — Major, Minor, or Diminished — helping you understand the harmonic structure.
Understanding Roman Numerals
Roman numeral analysis is a universal system for labeling chords relative to the key. Uppercase numerals (I, IV, V) indicate major chords, lowercase (ii, iii, vi) indicate minor chords, and numerals with a degree symbol (vii°) indicate diminished chords. This allows musicians to transpose progressions to any key easily.
Genre-Specific Patterns
- Pop: Clean, memorable progressions like I-V-vi-IV that appeal to broad audiences.
- Rock: Powerful progressions often incorporating the flat seventh (bVII) for edge.
- Jazz: Complex ii-V-I patterns with extended harmonies and smooth voice leading.
- Blues: The classic 12-bar pattern built on I, IV, and V with characteristic phrasing.
- Classical: Traditional cadential patterns emphasizing resolution and harmonic movement.
- EDM: Repetitive, uplifting progressions designed for electronic production and drops.
