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 Orgelbüchlein.Grout, Donald J. & Claude V. Palisca, A History of the Western Music 7º Edição, Norton, Londres, 2006.
==Function==
The liturgical function of a chorale prelude in the Baroque period is debated. One possibility is that they were used to introduce the hymn about to be sung by the congregation, usually in a Protestant, and originally in a Lutheran, church.
==Style==
Although it was typically a polyphonic setting, the melody would be plainly audible. There was sometimes an obbligato line above or below the melody.
As an independent genre, the chorale prelude began with the works of Dieterich Buxtehude, 48 of which are listed as extant in New Grove II. Numerous examples also exist from the 19th and 20th centuries, including some by Johannes Brahms and Max Reger. Works in the form continue to be composed in the present day.
==Form==
Most of the chorale prelude form is a theme and variation with a "long A" where the voices retrograde, invert, imitate while following the original basso continuo.
==Baroque period==
Probably, the earliest record of a melody used in chorale prelude by Johann Sebastian Bach is his arrangement of Gelobet seist du, Jesu Christ (BWV 604). this melody appears in a manuscript c1370, in the city of Celle. Later, it appears with an original text by Martin Luther, printed in the 'Geystliche Gesangk Buchleyn (edited by Johann Walter), in Wittenberg, 1524. In 1715, the hymn's book of Gotha, Gerrmany, had already printed thee melody of Gelobet seist du, Jesu Christ. Soon after, in 1717, Bach was requested by the Duke of Saxe Gotha to present a musical passion.[NBA, vols. III/2.1 & 2.2, Bärenreiter, 1954 to present; and the BWV "Bach Werke Verzeichnis", Breitkopf & Härtel, 1998.]
However, in a singular style, chorale prelude appeared first in the works of Dieterich Buxtehude (1637-1707), and includes 48 extensive compositions.[Sadie, Stanley and John Tyrell---editors. The New Grove Dictionary of Music and Musicians, 2nd edition, Oxford University Press, 2001.] 
Besides Bach, Pachelbel's music is of special importance, with many of his chorale preludes elaborated upon the Protestant melodies of Northern Germany.[Melville, Ruth. The Chorale Preludes of Johann Pachelbel. "Bulletin of the American Musicological Society, Nº3, pp.11-12. Apr., 1939.]
==Romantic period and twentieth century==
There are several examples of XIX and XX Century chorale preludes, for instance, the eleven works by Johannes Brahms a year before he died and published in 1902.[Bond, Ann. Brahms Chorale Preludes, op.122, "The Musical Times", Vol. 112, Nbr. 1543, pp. 898-900. September 1971.], also Max Reger's and Samuel Barber's.[Barber, Samuel. Dei Natali (Chorale Preludes for Christmas), 1960. Works such as these continue to be produced nowadays such as Helmut Walcha's four volumesChorale Prelude by Helmut Walcha - recordings, Cat. Opal-Libraries.org. Frankfurt, 1980 and the seven volumes of Flor Peeters.
