Chord progressions are written with Roman numerals relative to the key: I is the home chord, upper case is major, lower case is minor. The emotional effects below are common associations in Western music, shaped by tempo, rhythm and arrangement; they are tendencies, not rules.
I–V–vi–IV (the four-chord loop)
Bright, familiar and singable. Behind countless pop and rock songs. Slowed down it can sound nostalgic.
Prompt wording: "uplifting four-chord pop progression".
vi–IV–I–V
The same chords starting on the minor chord. Feels more bittersweet and emotional; common in ballads and EDM breakdowns.
Prompt wording: "bittersweet progression starting on the minor chord".
ii–V–I
The backbone of jazz. Smooth, sophisticated and resolved, especially with 7th and 9th chords.
Prompt wording: "jazz ii–V–I with 9th chords".
I–IV–V (12-bar blues)
Earthy and grounded, with dominant 7th chords. The basis of blues and early rock and roll.
Prompt wording: "12-bar blues shuffle".
i–VI–III–VII
Minor and epic. Common in film, game and trailer music, as well as synthwave.
Prompt wording: "epic minor progression for a trailer".
I–vi–IV–V
The "50s progression" of doo-wop ballads. Sweet and nostalgic.
Prompt wording: "50s doo-wop progression, sweet and nostalgic".
A single sustained chord
Static harmony feels hypnotic or meditative. Used in ambient music, techno and funk vamps.
Prompt wording: "one-chord vamp" or "static drone harmony".
Changing colour without changing progression
Swapping simple chords for 7ths, 9ths and suspended chords changes the mood without changing the progression. "With lush 9th chords" makes almost any progression feel softer and more sophisticated.
