La Juive and Capriccio are both examples of what type of performance?
Capriccio (opera) Capriccio, Op. 85, is the final opera by German composer Richard Strauss, subtitled "A Conversation Piece for Music". The opera received its premiere performance at the Nationaltheater München on 28 October 1942. Clemens Krauss and Strauss wrote the German libretto. However, the genesis of the libretto came from Stefan Zweig in the 1930s, and Joseph Gregor further developed the idea several years later. Strauss then took on the libretto, but finally recruited Krauss as his collaborator on the opera. Most of the final libretto is by Krauss.
Lazzi Lazzi ( ; from the Italian "lazzo", a joke or witticism) are stock comedic routines that are traditionally associated with "Commedia dell'arte". Performers, especially those playing the masked Arlecchino, had many of these "bits" in their repertoire, and would use improvisatory skills to weave them into the plot of dozens of different commedia scenarios. These largely physical sequences could be improvised or preplanned within the performance and were often used to enliven the audience when a scene was dragging, to cover a dropped line or cue, or to delight an expectant audience with the troupe's specialized lazzi.
