Carl Maria von Weber in the context of "Number opera"

Wilhelm Richard Wagner (/ˈvɑːɡnər/ VAHG-nər; German: [ˈvɪlˌhɛlm ˈʁɪçaʁt ˈvaːɡnɐ] ; 22 May 1813 – 13 February 1883) was a German composer, theatre director, essayist, and conductor, best known for his operas—although his mature works are often referred to as music dramas. Unlike most composers, Wagner wrote both the libretti and the music for all of his stage works. He first achieved recognition with works in the Romantic tradition of Carl Maria von Weber and Giacomo Meyerbeer, but revolutionised the genre through his concept of the Gesamtkunstwerk ("total work of art"), which sought to unite poetic, musical, visual, and dramatic elements. In this approach, the drama unfolds as a continuously sung narrative, with the music evolving organically from the text rather than alternating between arias and recitatives. Wagner outlined these ideas in a series of essays published between 1849 and 1852, most fully realising them in the first half of his four-opera cycle Der Ring des Nibelungen (The Ring of the Nibelung).

Wagner's compositions, particularly in his later period, have complex textures, rich harmonies and orchestration, and elaborate leitmotifs—musical phrases associated with individual characters, places, ideas, or plot elements. His advances in musical language, such as extreme chromaticism and quickly shifting tonal centres, greatly influenced the development of classical music; his Tristan und Isolde is regarded as an important precursor to modernist music. Later in life, he softened his ideological stance against traditional operatic forms (e.g., arias, ensembles and choruses), reintroducing them into his last few stage works, including Die Meistersinger von Nürnberg (The Mastersingers of Nuremberg) and Parsifal.

Orchestration is the study or practice of writing music for an orchestra (or, more loosely, for any musical ensemble, such as a concert band) or of adapting music composed for another medium for an orchestra. Also called "instrumentation", orchestration is the assignment of different instruments to play the different parts (e.g., melody, bassline, etc.) of a musical work. For example, a work for solo piano could be adapted and orchestrated so that an orchestra could perform the piece, or a concert band piece could be orchestrated for a symphony orchestra.

In classical music, composers have historically orchestrated their own music. Only gradually over the course of music history did orchestration come to be regarded as a separate compositional art and profession in itself. In modern classical music, composers almost invariably orchestrate their own work. Two notable exceptions to this are Ravel's orchestration of Mussorgsky's solo piano work Pictures at an Exhibition and Malcolm Arnold's orchestration of William Walton's String Quartet in A minor, producing the latter's Sonata for Strings.

John Cawse (25 December 1778 – 19 January 1862) was a British painter and caricaturist.

The Phantom of the Opera (French: Le Fantôme de l'Opéra, pronounced [lə fɑ̃tom də lɔpeʁa]) is a Gothic horror novel by French author Gaston Leroux. It was first published as a serial in Le Gaulois from 23 September 1909 to 8 January 1910, and was released in volume form in late March 1910 by Pierre Lafitte. The novel is partly inspired by historical events at the Paris Opera during the nineteenth century, and by an apocryphal tale concerning the use of a former ballet pupil's skeleton in an 1841 production of Carl Maria von Weber's Der Freischütz. It has been successfully adapted into various stage and film adaptations, most notable of which are the 1925 film depiction featuring Lon Chaney, and Andrew Lloyd Webber's 1986 musical.

Der Freischütz (J. 277, Op. 77 The Marksman or The Freeshooter) is a German opera with spoken dialogue in three acts by Carl Maria von Weber with a libretto by Friedrich Kind, based on a story by Johann August Apel and Friedrich Laun from their 1810 collection Gespensterbuch. It premiered on 18 June 1821 at the Schauspielhaus Berlin. It is considered the first German Romantic opera.

The opera's plot is mainly based on August Apel's tale "Der Freischütz" from the Gespensterbuch though the hermit, Kaspar and Ännchen are new to Kind's libretto. That Weber's tunes were just German folk music is a common misconception. Its unearthly portrayal of the supernatural in the famous Wolf's Glen scene has been described as "the most expressive rendering of the gruesome that is to be found in a musical score".

Christoph Martin Wieland (/ˈviːlənd/; German: [ˈviːlant]; 5 September 1733 – 20 January 1813) was a German poet and writer, representative of literary Rococo. He is best-remembered for having written the first Bildungsroman (Geschichte des Agathon), as well as the epic Oberon, which formed the basis for both Friederike Sophie Seyler's opera of the same name and Carl Maria von Weber's opera of the same name. His thought was representative of the cosmopolitanism of the German Enlightenment, exemplified in his remark: "Only a true cosmopolitan can be a good citizen." He was a key figure of Weimar Classicism and a collaborator of Abel Seyler's theatre company.

Germany claims some of the most renowned composers, singers, producers and performers of the world. Germany is the largest music market in Europe, and third largest in the world.

German classical music is one of the most performed in the world; German composers include some of the most accomplished, influential, and popular in history, among them Georg Friedrich Händel, Johann Sebastian Bach, Ludwig van Beethoven, Carl Maria von Weber, Felix Mendelssohn, Robert Schumann, Richard Wagner, Johannes Brahms and Richard Strauss, many of whom were among the composers who created the field of German opera.
