What is a riff?
In various popular music styles, riff refers to a brief, relaxed phrase repeated over changing melodies. It may serve as a refrain or melodic figure, often played by the rhythm section instruments or solo instruments that form the basis or accompaniment of a musical composition.
Though they are most often found in rock music, heavy metal music, Latin, funk and jazz, classical music is also sometimes based on a simple riff, such as Ravel’s Boléro. Riffs can be as simple as a tenor saxophone honking a simple, catchy rhythmic figure, or as complex as the riff-based variations in the head arrangements played by the Count Basie Orchestra.
David Brackett (1999) defines riffs as, “… short melodic phrases”, while Richard Middleton defines them as “short rhythmic, melodic, or harmonic figures repeated to form a structural framework”. Rikky Rooksby states, “A riff is a short, repeated, memorable musical phrase, often pitched low on the guitar, which focuses much of the energy and excitement of a rock song.”
