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.
Punctualism Punctualism (commonly also called "pointillism" or "point music") is a style of musical composition prevalent in Europe between 1949 and 1955 "whose structures are predominantly effected from tone to tone, without superordinate formal conceptions coming to bear" . In simpler terms: "music that consists of separately formed particles—however complexly these may be composed—[is called] punctual music, as opposed to linear, or group-formed, or mass-formed music" (, bolding in the source). This was accomplished by assigning to each note in a composition values drawn from scales of pitch, duration, dynamics, and attack characteristics, resulting in a "stronger individualizing of separate tones" . Another important factor was maintaining discrete values in all parameters of the music. Punctual dynamics, for example mean that all dynamic degrees are fixed; one point will be linked directly to another on the chosen scale, without any intervening transition or gesture. Line-dynamics, on the other hand, involve the transitions from one given amplitude to another: crescendo, decrescendo and their combinations. This second category can be defined as a dynamic glissando, comparable to glissandi of pitch and of tempi (accelerando, ritardando).
