By 1850, Wagner had completed a musical sketch (which he abandoned) for Siegfrieds Tod.[citation needed] He now felt that he needed a preliminary opera, Der junge Siegfried ("The Young Siegfried", later renamed to "Siegfried"), to explain the events in Siegfrieds Tod and his verse draft of this was completed in May 1851.[citation needed] By October, he had made the momentous decision to embark on a cycle of four operas, to be played over four nights: Das Rheingold, Die Walküre, Der Junge Siegfried and Siegfrieds Tod; the text for all four parts was completed in December 1852 and privately published in February 1853.[citation needed]
