Frequently asked questions
What is a chord progression generator?
A chord progression generator suggests an ordered series of chords for a song. This one builds progressions from your key, scale, mood, and genre, and shows Roman numerals, chord names, and notes.
How do mood and genre change the chords?
Mood chooses the harmonic shape, such as bright I–V–vi–IV for happy or ♭VI–♭VII moves for dark. Genre chooses fitting progressions and adds color: jazz uses seventh chords, blues uses dominant sevenths, and lo-fi adds add9 and seventh chords.
How do I transpose a progression?
Change the key or use the semitone arrows. The Roman numerals stay the same while chord names and notes are respelled for the new key signature, such as B♭ in F major or F♯ in D major.
Why does the minor key use a major V chord?
Minor progressions follow the natural minor scale, but dominant chords borrow the raised seventh from harmonic minor. That gives E–G♯–B in A minor for a stronger pull back to the tonic.
