8 major progressionsHow to use
- Pick a key (root note) and a mode (major or minor).
- Choose a preset progression, or build your own by clicking chords in the palette.
- Hit Play — each chord rings for a half-note at the chosen tempo.
Reading Roman numerals
Uppercase = major chord. Lowercase = minor. ° = diminished.
- I, IV, V — the bright "home" chords.
- ii, vi — the moody minors.
Writing tips
- Start with I. Pop and rock almost always do.
- End on I for resolution, V for tension.
- The vi chord is the secret weapon of sad pop — the relative minor.
