Problem: Given the question: Information: - In music, a fugue is a contrapuntal compositional technique in two or more voices, built on a subject (a musical theme) that is introduced at the beginning in imitation (repetition at different pitches) and which recurs frequently in the course of the composition. A fugue usually has three sections: an exposition, a development, and a final entry that contains the return of the subject in the fugue's tonic key. Some fugues have a recapitulation. In the Middle Ages, the term was widely used to denote any works in canonic style; by the Renaissance, it had come to denote specifically imitative works. Since the 17th century, the term "fugue" has described what is commonly regarded as the most fully developed procedure of imitative counterpoint. - The incipit of a text is the first few words of the text, employed as an identifying label. In a musical composition, an incipit is an initial sequence of notes, having the same purpose. The word "incipit" comes from Latin and means "it begins". - Johann Pachelbel (baptised September 1, 1653 buried March 9, 1706) was a German composer, organist, and teacher who brought the south German organ tradition to its peak. He composed a large body of sacred and secular music, and his contributions to the development of the chorale prelude and fugue have earned him a place among the most important composers of the middle Baroque era. - Approximately 530 compositions have been attributed to Johann Pachelbel . As of 2009 , no standard numbering system exists for Pachelbel 's work . This article presents a thematically organized list and provides catalogue numbers from three different catalogues : P = catalogue by Jean M. Perreault , 2001 T = catalogue by Hideo Tsukamoto , 2002 , available online ( archive from 18 October 2014 ) PC = catalogue by Kathryn J. Welter , 1998 For organ works , POP catalogue numbers are provided , from catalogue by Antoine Bouchard for his 1998 -- 2001 recording of Pachelbel 's organ oeuvre ( this catalogue only covers organ works ) . Perreault numbers are used as the basis of the list , making individual sections organized alphabetically ( i.e. the chorales ) and / or by tonality . Because the Welter catalogue does not provide incipits , many of the works with identical titles will share a single PC number ( which is in such cases denoted by a question mark ) . The following symbols are used : * denotes that the ascription of the piece is questioned ! denotes that the composition is , apparently , lost Similarly to catalogues of works by most early music composers , Pachelbel 's list of works remains perpetually incomplete as new works are regularly found . - The Baroque (or ) is often thought of as a period of artistic style that used exaggerated motion and clear, easily interpreted detail to produce drama, tension, exuberance, and grandeur in sculpture, painting, architecture, literature, dance, theater, and music. The style began around 1600 in Rome and Italy, and spread to most of Europe. - In music, a chorale prelude is a short liturgical composition for organ using a chorale tune as its basis. It was a predominant style of the German Baroque era and reached its culmination in the works of J.S. Bach, who wrote 46 (with a 47th unfinished) examples of the form in his Orgelbuchlein.
