Chord Progression Generator — Tips & Guide
Generate complete song chord progressions for verse, pre-chorus, chorus, and bridge sections. All progressions stay in the same key for harmonic consistency.
Lock Sections You Love

Start with Major Keys
For pop, folk, and upbeat songs, start with a major key. Minor keys work better for emotional, dark, or introspective material. Both are available in the key selector.
The I-IV-V is Timeless
The I-IV-V chord progression underlies thousands of pop, rock, and blues songs. It's universally recognized as satisfying because of the strong tension-and-release relationship between V and I.
Use the vi for Emotional Depth
Adding the vi chord (relative minor) to a major progression adds emotional nuance. The I-V-vi-IV progression is one of the most-used in modern pop music for this reason.
Contrast Verse and Chorus
Make your chorus feel like a release by using the I chord prominently. Keep verses more harmonically restless (ii, IV, vi) to build tension that the chorus can resolve.
Borrow Chords for Surprise
Borrowed chords (from a parallel major or minor key) create unexpected emotion. A bIII or bVII chord in a major key adds a dramatic, cinematic quality to your bridge.
A chord progression is a sequence of chords played one after another, forming the harmonic backbone of a song section. Chords are labeled using Roman numerals (I, ii, iii, IV, V, vi, vii) to show their relationship to the key. Uppercase numerals indicate major chords; lowercase indicate minor. A progression like I-V-vi-IV in C major means C major - G major - A minor - F major, one of the most recognizable progressions in modern music.
The I-IV-V progression is the most fundamental in Western music. In C major it is C major, F major, G major. The V chord creates harmonic tension that naturally wants to resolve back to the I, giving the progression a satisfying push-and-pull quality. It forms the basis of blues, rock and roll, country, and folk music. Adding a I-IV-V-I back to the tonic completes the harmonic circle. This three-chord progression has been the foundation of songs from Johnny B. Goode to La Bamba.
Start by choosing a key and scale (major for bright, uplifting songs; minor for dark or emotional ones). Pick 3–4 chords that feel good together — the I, IV, V, and vi are safe starting points in any key. Arrange them in a 4-bar loop and play or sing over the top. Once you have a verse progression, modify it slightly for the chorus — often starting on a different chord or using a stronger V-I resolution. Use this generator to explore hundreds of possibilities in seconds.
Chords that belong to the same key naturally go together. In a major key (e.g., C major), the seven diatonic chords are: I (C major), ii (D minor), iii (E minor), IV (F major), V (G major), vi (A minor), vii° (B diminished). Any combination of these chords will sound harmonically coherent. The most popular pairs are I-IV, IV-V, V-I, I-vi, and vi-IV. Unexpected combinations like IV-I or vi-V add variety. The generator explores all these relationships automatically.
