Claude Ballif (22 May 1924 in Paris – 24 July 2004 in Poissons) was a French composer. His music is known as a combination of tonality (in the sense of Bartók, for instance) and serialism - a system that he named metatonality. Claude Ballif was a committed pedagogue who taught composition and analysis at the Paris Conservatoire from 1971 to 1990. Following this, he taught the same subjects at the Sevran conservatory. His pupils included Raynald Arseneault, Nicolas Bacri, Gérard Buquet, Alexandre Desplat, Joseph-François Kremer, Philippe Manoury, and Mehmet Okonsar.
