Creep (Radiohead song) in the context of "Pablo Honey"

A riff is a short, repeated motif or figure in the melody or accompaniment of a musical composition. Riffs are most often found in various genres of rock music (including punk and heavy metal music), as well as Latin, funk, and jazz, although classical music is also sometimes based on a riff, as in 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 (1999) defines them as "short rhythmic, melodic, or harmonic figures repeated to form a structural framework". Author 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."

Radiohead are an English rock band formed in Abingdon, Oxfordshire, in 1985. The band members are Thom Yorke (vocals, guitar, keyboards); the brothers Jonny Greenwood (guitar, keyboards, other instruments) and Colin Greenwood (bass); Ed O'Brien (guitar, backing vocals); and Philip Selway (drums). They have worked with the producer Nigel Godrich and the cover artist Stanley Donwood since 1994. Radiohead's experimental approach is credited with advancing the sound of alternative rock.

Radiohead signed to EMI in 1991 and released their debut album, Pablo Honey, in 1993. Their debut single, "Creep", was a worldwide hit, and their popularity and critical standing rose with The Bends in 1995. Their third album, OK Computer (1997), is acclaimed as a landmark record and one of the greatest albums in popular music, with complex production and themes of modern alienation. Their fourth album, Kid A (2000), marked a dramatic change in style, incorporating influences from electronic music, jazz, classical music and krautrock. Though Kid A divided listeners, it was later named the best album of the decade by multiple outlets. It was followed by Amnesiac (2001), recorded in the same sessions. Radiohead's final album for EMI, Hail to the Thief (2003), blended rock and electronic music, with lyrics addressing the war on terror.
