What is "gassenhauer"

Gassenhauer nach Hans Neusiedler (1536), commonly known as Gassenhauer , is a short piece from Carl Orff's Schulwerk. As the full title indicates, it is either an arrangement of, or inspired by, a much older work by the lutenist Hans Neusiedler from 1536. It (along with several other pieces) is in fact credited to Orff's longtime collaborator, Gunild Keetman, on at least one recent release of the Schulwerk. As with many other pieces from the Schulwerk, it has been used multiple times on television, radio, and in films, including the films Badlands (1973), Ratcatcher (1999), Finding Forrester (2000), Monster (2003), and, most recently, Michael Moore's Capitalism: A Love Story (2009) and The Simpsons′ 22nd season episode " The Scorpion's Tale" (2011). The piece was used as the theme music for an afternoon radio program also titled Gassenhauer on the classical music station WCLV in Cleveland, Ohio, in the 1970s.
