Crazy Little Thing Called Love

The harmony of 'Crazy Little Thing Called Love' is a masterclass in simplicity. Built on just a handful of chords, it draws from the rockabilly and blues traditions with its prominent bVI-bVII-I cadence — a hallmark of 1950s rock and roll. Mercury's self-imposed limitation of writing on an instrument he barely played resulted in a chord palette that is both stripped-down and perfectly suited to the song's retro energy. Brian May's solo adds melodic sophistication without complicating the harmonic foundation.

Freddie Mercury composed the song on guitar — an instrument he admitted he could barely play — while relaxing in a bath at the Hotel Bayerischer Hof in Munich. The limited chord vocabulary forced him to write within a tight framework, which he later credited as a creative discipline that produced a stronger song. He presented the finished lyrics to Roger Taylor and John Deacon shortly afterward.

Written by Freddie Mercury in just five to ten minutes on a guitar he could barely play, 'Crazy Little Thing Called Love' channels 1950s rock and roll energy through a British rock lens. Released in 1979 as the lead single from The Game, it topped the Billboard Hot 100 for four consecutive weeks, proving Queen could master any genre they touched.
