The Sonata for Solo Cello is an unaccompanied cello sonata written by György Ligeti between 1948 and 1953. The piece was initially received poorly by the Soviet-run Composer's Union and was not allowed to be published or performed. However, in the 1980s and 90s, after over a quarter century in repose, the piece reemerged and has since become a well-known part of the standard cello repertoire.
