Rundkanzone [German: "rounded chanson" or "rounded [[canzona]]"] is a type of bar form (AAB form or "canzona form") originally taken from medieval German song, but also used to describe musical form in general. The form is represented by either:
The second part (CB) [German: ''[[Abgesang]]] concludes with most or all of the material (B) from each half (AB) [German: ''[[Stollen]]] of the double first part (ABAB) [German: ''Aufgesang''].
German terms are retained in the discussion of bar form by music scholars because the terms were introduced by Lorenz[3] in his exhaustive investigation of the music of 19th-century composer Richard Wagner.
