There are happy chord progressions, sad chord progressions, simple chord progressions and very complex chord progressions. But even simple, repetitive progressions of chords have the power to convey a complex array of emotions and musical ideas. One major, minor or diminished chord can’t do much storytelling on their own. A certain chord at a certain time in a chord progression can drastically change the narrative of your song from happy to sad or dark to light with one simple chord choice. They also play a big part in the narrative of your song.
From Beach House to Beethoven, chord progressions determine how a piece of music unfolds over time.
