Josep Ferran Sorts i Muntades (baptised 14 February 1778 – died 10 July 1839, Paris) was a Spanish classical guitarist and composer. He is best known for his guitar compositions, but he also composed music for opera and ballet, earning acclaim for his ballet titled Cendrillon. Sor’s works for guitar range from pieces for advanced players, such as Variations on a Theme of Mozart, to beginner pieces.
Sor gave concerts throughout Europe, including in England, Paris, Berlin and Warsaw. Before the early 19th century, the guitar was little-known in England. Sor seems to have created a market for himself there and then met the demand. Sor’s contemporaries considered him to be the best guitarist in the world, and his works for guitar have been widely played and reprinted since his death.
As Sor's works were published in various countries, his name was translated, leading to variations in the spelling. Variations have included Joseph Fernando Macari Sors, Fernando Sor, Ferran Sor, Ferdinand Sor, and Ferdinando Sor.
