So what the hell is a riff anyway? There are numerous definitions out there, but most are along these lines: “a short rhythmic musical phrase which may be repeated often during a piece.”

Through the decades as folk begat blues, blues got rhythm then spawned rock ‘n’ roll and its many bastard offspring, the guitar riff became king, sometimes even usurping the vocal melody as a song’s main calling card.
