German: Posse mit Gesang ("farce with singing", plural: German: Possen) is a form of popular German-language music drama, that developed in the late 18th and early 19th centuries. Early examples are sometimes called German: Possenspil or German: Possenspiel. It is also sometimes referred to simply as German: Posse (farce).
Associated with Vienna, and also Berlin and Hamburg, the German: Posse mit Gesang was similar to the Singspiel, but generally had more action and less music than the more operatic form. Viennese examples included Ferdinand Raimund's German: Der Alpenkönig und der Menschenfeind of 1828 and many of the works of Johann Nestroy. Composers who contributed music for German: Posse included Wenzel Müller, Conradin Kreutzer, and Philip Jakob Riotte.
Some 20th-century examples of posse written by Walter Kollo were German: [[Filmzauber]] (1912) and German: {{Ill|Wie einst im Mai (operetta)|de|3=Wie einst im Mai|lt=Wie einst im Mai (1913).
More specialized examples of the genre were German: Lokalposse (daily life themes), German: Zauberposse (magic), German: Charakterposse (personalities), German: Situationsposse (situations), and German: Parodierende Posse (parodies).
