Common practice period

Early Baroque organ music in Germany was highly contrapuntal. Sacred organ music was based on chorales: composers such as Samuel Scheidt and Heinrich Scheidemann wrote chorale preludes, chorale fantasias, and chorale motets. Near the end of the Baroque era, the chorale prelude and the partita became mixed, forming the chorale partita. This genre was developed by Georg Böhm, Johann Pachelbel, and Dieterich Buxtehude. The primary type of free-form piece in this period was the praeludium, as exemplified in the works of Matthias Weckmann, Nicolaus Bruhns, Böhm, and Buxtehude. The organ music of Johann Sebastian Bach fused characteristics of every national tradition and historical style in his large-scale preludes and fugues and chorale-based works. George Frideric Handel composed the first organ concertos.

In France, organ music developed during the Baroque era through the music of Jean Titelouze, François Couperin, and Nicolas de Grigny. Because the French organ of the 17th and early 18th centuries was very standardized, a conventional set of registrations developed for its repertoire. The music of French composers (and Italian composers such as Girolamo Frescobaldi) was written for use during the Mass. Very little secular organ music was composed in France and Italy during the Baroque period; the written repertoire is almost exclusively intended for liturgical use. In England, composers such as John Blow and John Stanley wrote multi-sectional free works for liturgical use called voluntaries through the 19th century.

Organ music was seldom written in the Classical era, as composers preferred the piano with its ability to create dynamics. In Germany, the six sonatas op. 65 of Felix Mendelssohn (published 1845) marked the beginning of a renewed interest in composing for the organ. Inspired by the newly built Cavaillé-Coll organs, the French organist-composers César Franck, Alexandre Guilmant and Charles-Marie Widor led organ music into the symphonic realm. The development of symphonic organ music continued with Louis Vierne and Charles Tournemire. Widor and Vierne wrote large-scale, multi-movement works called organ symphonies that exploited the full possibilities of the symphonic organ, such as Widor's Symphony for Organ No. 6 and Vierne's Organ Symphony No. 3. Max Reger and Sigfrid Karg-Elert 's symphonic works made use of the abilities of the large Romantic organs then built in Germany.

In the 19th and 20th centuries, organ builders began to build instruments in concert halls and other large secular venues, allowing the organ to be used as part of an orchestra, as in Saint-Saëns' Symphony No. 3 (sometimes known as the Organ Symphony). Frequently the organ is given a soloistic part, such as in Joseph Jongen 's Symphonie Concertante for Organ & Orchestra, Francis Poulenc 's Concerto for Organ, Strings and Tympani, and Frigyes Hidas' Organ Concerto.
