Dada In February 1918, while the Great War was approaching its climax, Huelsenbeck gave his first Dada speech in Berlin, and he produced a Dada manifesto later in the year. Following the October Revolution in Russia, by then out of the war, Hannah Höch and George Grosz used Dada to express communist sympathies.

Art song Art songs have been composed in many languages, and are known by several names. The German tradition of art song composition is perhaps the most prominent one; it is known as Lieder. In France, the term mélodie distinguishes art songs from other French vocal pieces referred to as chansons. The Spanish canción and the Italian canzone refer to songs generally and not specifically to art songs.
