8 major progressionsHow to use

- 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.

Frequently asked questions
- What is a chord progression?
- A chord progression is a sequence of chords played in order. The most common progressions in pop are I–V–vi–IV and I–IV–V, which appear in thousands of songs across genres.
- How do I generate a chord progression?
- Pick a key and choose a pattern. The generator shows the chords in that key so you can hear how they move and decide what fits the mood of your song.
- What key should I write in?
- Any key works — the relationships between chords are the same in all keys. C major is often chosen for beginners because it has no sharps or flats. Choose based on the instrument range or vocal key that suits the performer.
