The most famous trick in pop music
Here is a secret that songwriters have leaned on for decades: an enormous number of hit songs are built on the same four chords. Musicians call it the I–V–vi–IV progression.
In the key of C that is: C G Am F
Learn those four shapes and you can play along with Bob Marley, Adele, Journey, U2, The Beatles and countless more — often large sections of the song. That is the magic of playing by ear. You are not reading a single note, you are hearing how songs are actually put together.
Below are some of the most recognisable songs built on these four chords. Watch the videos, then try them yourself.
