The progressions

  • Pop anthemI V vi IV

    Big, hopeful, singable. One of the most used progressions in pop.

  • Sensitivevi IV I V

    The same four chords starting on the minor: wistful, then lifting.

  • FiftiesI vi IV V

    Doo-wop and slow-dance warmth.

  • LiftIV I V vi

    Starts away from home, so it feels like it is always reaching.

  • Slow burnI iii IV V

    Tender, with a gentle ache on the iii chord.

  • HymnI IV I V

    Plain and honest; leaves room for the words.

  • Three chordsI IV V

    The backbone of folk, country and rock and roll.

  • HighwayI bVII IV I

    Open-road rock: the borrowed ♭VII gives it swagger.

  • HeartlandI bVII IV IV

    Jangly, wide-open guitar rock.

  • 12-bar bluesI7 I7 I7 I7 IV7 IV7 I7 I7 V7 IV7 I7 V7

    Twelve bars that most of rock and roll grew out of.

  • Andalusiani VII VI V

    A falling bass line with Spanish drama.

  • Night drivei VI III VII

    Dark but moving forward; huge in film and alt-pop.

  • Two-five-oneii7 V7 Imaj7

    The basic cadence of jazz standards.

How to use it to write

Set the tempo a little slower than feels natural, loop one progression, and sing nonsense syllables over it. When a phrase repeats itself twice, that's your hook. Change the groove before you change the chords: the same four chords feel completely different as a ballad and as a shuffle.
