A contrafact is a musical composition built using the chord progression of a pre-existing song, but with a new melody and arrangement.
Typically the original tune's progression and song form will be reused but occasionally just a section will be reused in the new composition.
The term comes from classical music and was first applied to jazz by musicologists in the 1970s and 1980s.
[citation needed] Contrafacts by notable jazz artists include: B "Honeysuckle Rose"
B Fats Waller B "Le Petit Cireur Noir "You Don't Know What Love Is" Gene De Paul
