Schaffel (the German phonetic spelling of "shuffle") is a term used to describe a style in progressive electronic music in which the beat is shuffled hard. Often triplet eights are used to create swinging rhythms.
Originating from swing and R&B roots, the beat was popularized by glam rock performers like T.Rex with their 1971 hit "Hot Love" and Gary Glitter in his 1972 hit "Rock and Roll Pt 2"[1]. An early use of the beat in an electronic pop song was Iggy Pop's "Nightclubbing" from his album The Idiot (1977). A recent example is Muse's 2009 single Uprising.
The Schaffel beat has remained in use in electronic music genres and can be found in such releases as "Personal Jesus" by Depeche Mode[1], "Like Tears in Rain" by Covenant, "Love etc." by Pet Shop Boys and "Wasted (Naghavi Mix)" by And One.
Michael Mayer's label Kompakt has put out a series of compilations titled Schaffelfieber.
