A prelude (Germ. Präludium or Vorspiel; Lat. praeludium; Fr. Prélude; It. Preludio) is a short piece of music, the form of which may vary from piece to piece. While, during the Baroque Age, for example, it may have served as an introduction to succeeding movements of a work that were usually longer and more complex, it may also have been a stand alone piece of work during the Romantic Era. It generally features a small number of rhythmic and melodic motifs that recur through the piece. Stylistically, the prelude is improvisatory in nature. The prelude can also refer to an overture, particularly to those seen in an opera or an oratorio.
The prelude can be thought of as a preface. It may stand on its own or introduce another work. Johann Sebastian Bach's (1685-1750) "prelude and fugue" pieces are much more numerous and well-known today. Bach's organ preludes are quite diverse, drawing on both southern and northern German influences. Most of Bach's preludes were written in the theme and variation form, using the same theme motif with imitation, inversion, modulation, or retrograde the theme as well as other techniques involved in this baroque form.Bach's Well-Tempered Clavier influenced almost all major composers of the next centuries, and many often wrote preludes in sets of 12 or 24, sometimes with the intention of utilizing all 24 major and minor keys as Bach had done. Johann Sebastian Bach wrote the two volumes of the Well-Tempered Clavier (1722, 1744). Both volumes contain 24 preludes (and associated fugues) proceeding up the chromatic scale with alternating parallel major and minor keys (C major and C minor; C# major and C# minor;D major and D minor; etc). In music, a fugue (pronounced /ˈfjuːɡ/) is a type of contrapuntal composition or technique of composition for a fixed number of parts, normally referred to as "voices".The English term fugue originates in the 16th century and is derived from either the French fugue or Italian fuga, which in turn comes from Latin, also fuga, which is itself related to both fugere (‘to flee’) and fugare, (‘to chase’). The adjectival form is fugal. Variants include fughetta (literally, 'a small fugue') and fugato (a passage in fugal style within another work that is not a fugue).The Well-Tempered Clavier (Das Wohltemperierte Klavier in the original German), BWV 846–893, is a collection of solo keyboard music composed by Johann Sebastian Bach. He first gave the title to a book of preludes and fugues in all 24 major and minor keys, dated 1722, composed "for the profit and use of musical youth desirous of learning, and especially for the pastime of those already skilled in this study." Bach later compiled a second book of the same kind, dated 1742, but titled it only "Twenty-four Preludes and Fugues." The two works are now usually considered to comprise the Well-Tempered Clavier and are referred to respectively as Books I and II. The Well-Tempered Clavier is generally regarded as one of the most influential works in the history of Western classical music.Johann Sebastian Bach (German pronunciation: [joˈhan] or [ˈjoːhan zeˈbastjan ˈbax]) (31 March 1685 [O.S. 21 March] – 28 July 1750) (often referred to as Bach) was a German composer and organist whose ecclesiastical and secular works for choir, orchestra, and solo instruments drew together the strands of the Baroque period and brought it to its ultimate maturity. Although he introduced no new forms, he enriched the prevailing German style with a robust contrapuntal technique, an unrivalled control of harmonic and motivic organisation, and the adaptation of rhythms, forms and textures from abroad, particularly Italy and France.Bach's abilities as an organist were highly respected throughout Europe during his lifetime, although he was not widely recognised as a great composer until a revival of interest and performances of his music in the first half of the 19th century. He is now regarded as the greatest composer of the Baroque, and as one of the greatest of all time.
