[1]  [DOC] Doktor Faust is an opera by Ferruccio Busoni with a German libretto by the composer himself, based on the myth of Faust. Busoni worked on the opera, which he intended as his masterpiece, between 1916 and 1924, but it was still incomplete at the time of his death. His pupil Philipp Jarnach finished it. More recently, in 1982, Antony Beaumont completed the opera using sketches by Busoni which were previously thought to have been lost. Nancy Chamness has published an analysis of the libretto to "Doktor Faust" and a comparison with Goethe's version. [END]
