Smoke on the Water was released by Deep Purple in 1972 on the album Machine Head, and its simple four-note guitar riff quickly became one of the most recognisable openings in rock music. The riff is famously one of the first many guitar learners play, which has helped it stay in popular culture for decades. Flute versions, like this one, turn that familiarity into comedy by playing the heavy riff on a much softer instrument. Online, the contrast is often used in short videos, memes and edits that need an instantly known tune without a serious tone.
