Popular templates included
Start from proven forms like I-V-vi-IV, ii-V-I, I-vi-IV-V, i-VI-III-VII, i-iv-V, and i-VI-VII. The tool transposes each one into your selected key.
Write faster with Roman numerals
Roman numerals show the function of each chord, so you can move an idea from C major to Eb major or from A minor to F minor without rebuilding the harmony by ear.
How to shape the generated ideas
Keep the generated chords, then change rhythm, voicing, inversions, bass movement, and extensions. The same I-V-vi-IV loop can become a piano ballad, guitar chorus, or synth-pop hook depending on where the chords land in the bar.
Major vs minor mode
Major mode favors brighter tonic motion and common pop cadences. Minor mode keeps the tonic darker and often uses VI, VII, iv, or a major V for stronger pull back to i.
Frequently Asked Questions
What does the chord progression generator create?
It creates short, usable harmonic loops for songwriting. Each result shows both Roman numerals and chord names in your selected key.
Can I use these progressions in my own songs?
Yes. Chord progressions are building blocks, not complete songs. You can use, change, transpose, and record them freely.
Why do some minor progressions use a major V chord?
A major V in minor keys is common because it creates a stronger pull back to i. For example, A minor can use E major before resolving to Am.
What are Roman numerals for?
Roman numerals describe scale degrees independent of key. I-V-vi-IV has the same function in C major and Bb major, even though the chord names change.
