Musical genre related to the serenade and divertimento
the legal term
Cassation is a minor musical genre related to the serenade and divertimento. In the mid to late 18th century, cassations commonly comprised loosely assembled sets of short movements intended for outdoor performance by orchestral or chamber ensembles. The genre was popular in southern German speaking lands. Other synonymous titles used by German speaking composers and cataloguers included Cassatio, Cassatione and Kassation. An equivalent Italian term was Cassazione. The genre is occasionally alluded to in the titles of some twentieth century compositions.

Works titled cassation were especially common in southern Germany, Austria and Bohemia in the mid to late part of the eighteenth century. The Toy Symphony (no known author) was a reduction of an earlier Cassation in G. The Italianized term, cassazione, appears to have been used by Antonio Salieri. It is hard to discern any substantial formal characteristic that could distinguish cassations from other serenade like genres, such as the divertimento, notturno, or Finalmusik. Breitkopf's thematic catalogues of the time tended to apply titles such as "cassation" and "divertimento" rather interchangeably, as did the composers themselves. Cassazione is the title of an orchestral piece in a single movement by Jean Sibelius, and of a string sextet by Riccardo Malipiero.

The etymology of the musical term is uncertain.|group= n implying a musical farewell, or Abschiedsmusik.
