Answer the following question: Information: - A composer (Latin "compn"; literally "one who puts together") is a person who creates or writes music, which can be vocal music (for a singer or choir), instrumental music (e.g., for solo piano, string quartet, wind quintet or orchestra) or music which combines both instruments and voices (e.g., opera or art song, which is a singer accompanied by a pianist). The core meaning of the term refers to individuals who have contributed to the tradition of Western classical music through creation of works expressed in written musical notation (e.g., sheet music scores). - An author is narrowly defined as the originator of any written work and can thus also be described as a writer (with any distinction primarily being an implication that an author is a writer of one or more major works, such as books or plays). More broadly defined, an author is "the person who originated or gave existence to anything" and whose authorship determines responsibility for what was created. The more specific phrase published author refers to an author (especially but not necessarily of books) whose work has been independently accepted for publication by a reputable publisher , versus a self-publishing author or an unpublished one . - Franz Liszt (born Franz Joseph Liszt) (in modern usage "Liszt Ferenc", ; October 22, 1811July 31, 1886) was a prolific 19th-century Hungarian composer, virtuoso pianist, conductor, music teacher, arranger, organist, philanthropist, author, nationalist and a Franciscan tertiary. - A libretto is the text used in, or intended for, an extended musical work such as an opera, operetta, masque, oratorio, cantata or musical. The term "libretto" is also sometimes used to refer to the text of major liturgical works, such as the Mass, requiem and sacred cantata, or the story line of a ballet. - Wilhelm Richard Wagner (22 May 181313 February 1883) was a German composer, theatre director, polemicist, and conductor who is primarily known for his operas (or, as some of his later works were later known, "music dramas"). Unlike most opera composers, Wagner wrote both the libretto and the music for each of his stage works. Initially establishing his reputation as a composer of works in the romantic vein of Weber and Meyerbeer, Wagner revolutionised opera through his concept of the "Gesamtkunstwerk" ("total work of art"), by which he sought to synthesise the poetic, visual, musical and dramatic arts, with music subsidiary to drama. He described this vision in a series of essays published between 1849 and 1852. Wagner realised these ideas most fully in the first half of the four-opera cycle "Der Ring des Nibelungen" ("The Ring of the Nibelung"). - Nike Wagner ( born on 9 June 1945 at Uberlingen on Lake Constance in Germany ) is a German arts administrator and scholar .

Her article questioning the propriety of public subsidies given to high - profile cultural events in general , and the Bayreuth Festival in particular ( at present c.US $ 6.5 million annually ) , Im Fadenkreuz der Kulturpolitik , published in the July 2006 issue of Cicero : Magazin fur politische Kultur , engendered controversy within Germany . In 2004 , Wagner became the director of the Kunstfest Weimar , later renamed the Pelerinages Festival in honour of Liszt . She stood down from the post in September 2013 .

In traditional opera, singers do two types of singing: recitative, a speech-inflected style and arias, a more melodic style. Opera incorporates many of the elements of spoken theatre, such as acting, scenery, and costumes and sometimes includes dance. The performance is typically given in an opera house, accompanied by an orchestra or smaller musical ensemble, which since the early 19th century has been led by a conductor. - A Gesamtkunstwerk (translated as "total work of art", "ideal work of art", "universal artwork", "synthesis of the arts", "comprehensive artwork", "all-embracing art form" or "total artwork") is a work of art that makes use of all or many art forms or strives to do so. The term is a German word which has come to be accepted in English as a term in aesthetics. - A virtuoso (from Italian "virtuoso" or , "virtuous", Late Latin "virtuosus", Latin "virtus", "virtue", "excellence", "skill", or "manliness") is an individual who possesses outstanding technical ability in a particular art or field such as fine arts, music, singing, playing a musical instrument, or composition. This word also refers to a person who has cultivated appreciation of artistic excellence, either as a connoisseur or collector.

Most forms of Western music can make use of the piano. Consequently, pianists have a wide variety of repertoire and styles to choose from, including traditionally classical music, Jazz, blues and all sorts of popular music, including rock music. Most pianists can, to a certain extent, play other keyboard-related instruments such as the synthesizer, harpsichord, celesta and the organ and keyboard. Perhaps the greatest pianist of all time was Franz Liszt, whose piano mastery was described by Anton Rubinstein: "In comparison with Liszt, all other pianists are children". - A polemic is contentious rhetoric that is intended to support a specific position. Polemics are mostly seen in arguments about controversial topics. The practice of such argumentation is called "polemics". A person who often writes polemics, or who speaks polemically, is called a "polemicist". The word is derived , .
