"Mack the Knife" was composed by Kurt Weill in 1928 for the music drama The Threepenny Opera (Die Dreigroschenoper), with German lyrics by Bertolt Brecht. Originally titled "Die Moritat von Mackie Messer," the song is a murder ballad depicting a knife-wielding criminal of the London underworld.

The tune features an elegantly simple strophic form—a repeating 16-bar structure over a basic chord progression—most commonly played in the key of Bb major. In jazz performance, the standard approach involves modulating up by a half step with each new chorus, building excitement and intensity as the piece progresses. The melody sits comfortably within an octave, making it ideal for vocalists, while the straightforward harmony gives soloists freedom to explore rhythmic invention and dynamic phrasing rather than navigating complex changes.

The definitive jazz recordings include Louis Armstrong's 1955 version, which introduced the song to American audiences, and Ella Fitzgerald's legendary 1960 live performance on Mack the Knife: Ella in Berlin, where she famously forgot the lyrics mid-performance and improvised her way through with brilliant scat singing, earning a Grammy Award.
