Busoni never came closer to his dream of Italian music than with that night on May 11 1917 of double performance in Zurich, which he calls himself 'La Nuova Commedia dell' Arte' I ('Turandot') and II ('Arlecchino'). In the unusually short time from December 1916 to March 1917 Busoni reworked the already existing material to the Incidental Music of Gozzis 'Turandot' into an opera. This happen 4 years before Puccini started to work on the same contend. 'Arleccino', though in immediate neighbourhood to 'Dr. Faust' looking almost like a secondary work, is perhaps the composer's actual key work. The speaking hero of his 'theatralische Capriccio' represents a role model, which is at times more important to him than his aesthetic Faust, especially as the the World War increases.
