Common progressions in Bb minor

Six patterns that show up again and again in songs written in this key. The chord names are spelled out in Bb minor so you can drop them straight into a verse or chorus.

i→VI→III→VII

The minor anthem

Bbm - Gb - Db - Ab

Heroic minor four-chord. The descent from i to VI to III gives the verse weight, VII slingshots back to the tonic. The Andalusian cousin of the pop axis.

Heard in: 'Save Tonight' by Eagle-Eye Cherry, 'Zombie' by The Cranberries, 'Numb' by Linkin Park

i→VII→VI→VII

The modal lament

Bbm - Ab - Gb - Ab

Three chords down, one back up. Drone-like and modal, common in folk-rock and Britpop. The VII to VI walk gives a wistful sigh.

Heard in: 'Stairway to Heaven' by Led Zeppelin (intro), 'All Along the Watchtower' by Bob Dylan, 'House of the Rising Sun' by The Animals

i→iv→V→i

Harmonic minor cadence

Bbm - Ebm - Fm - Bbm

The classical pull. The V is borrowed from harmonic minor (a major V instead of v), creating a sharper push back to the tonic. Used in flamenco, classical and metal alike.

Heard in: 'Hit the Road Jack' by Ray Charles, 'Black Magic Woman' by Santana, 'Sultans of Swing' by Dire Straits

i→VI→VII→i

Andalusian climb

Bbm - Gb - Ab - Bbm

A relative of the descending Andalusian cadence, reordered. Opens dark, lifts through VI and VII, lands firm. Sounds Spanish but turns up in metal and trap.

Heard in: 'Smooth' by Santana feat. Rob Thomas, 'Sweet Dreams' by Eurythmics, 'Hotel California' by Eagles

i→III→VII→VI

The cinematic minor

Bbm - Db - Ab - Gb

Spacious and filmic. The III chord is the relative major, providing a brief lift before the song descends again. A staple of trailer music and indie ballads.

Heard in: 'Mad World' by Tears for Fears, 'Bad Romance' by Lady Gaga, 'Radioactive' by Imagine Dragons

i→iv→VII→III

Cycle-of-fifths minor

Bbm - Ebm - Ab - Db

Each chord pulls cleanly to the next around the cycle of fifths. Used in jazz minor turnarounds and many Latin progressions.

Heard in: 'Hit the Road Jack' by Ray Charles, 'Wake Me Up When September Ends' by Green Day, 'I Will Survive' by Gloria Gaynor

Borrowed chords for Bb minor

Chords pulled in from the parallel key to add colour. These four are the ones songwriters reach for most often when Bb minor starts to feel too plain.

From harmonic minor (V)

Replaces the natural v with a major V chord. The leading tone in the V gives a much stronger pull back to the tonic.

From parallel major (IV)

The bright IV inside a minor key. A common move in modal pop and folk that hints at the parallel major without committing.

From parallel major (Picardy)

Ending a minor song on the major tonic. A classical trick (the Picardy third) still used in jazz and gospel for surprise resolution.

From parallel major (ii)

Borrowed as a passing colour. Sits a half-step above the diatonic ii° and feels less sour, opening a smoother turnaround.

Why songwriters reach for Bb minor
