Sinfonia Antartica (Antarctic Symphony) is the Italian title given by the English composer Ralph Vaughan Williams to his seventh symphony.
Vaughan Williams provided the music for the film Scott of the Antarctic in 1947, and was so inspired by the subject that he incorporated much of the music into a symphony. The piece was begun in 1949, and composition completed in 1952, with a dedication to Ernest Irving.
The first performance took place on 14 January 1953 in Manchester with Sir John Barbirolli conducting the Hall? Orchestra; the soprano soloist was Margaret Ritchie.
The work is scored for a large orchestra.There is also a wordless three-part women's chorus and solo soprano, which sing only in the first and last movements.
