In classical music, a fugue is a contrapuntal, polyphonic compositional technique in two or more voices, built on a subject that is introduced at the beginning in imitation, which recurs frequently throughout the course of the composition. It is not to be confused with a fuguing tune, which is a style of song popularized by and mostly limited to early American music and West Gallery music. A fugue usually has three main sections: an exposition, a development, and a final entry that contains the return of the subject in the fugue's tonic key. Fugues can also have episodes—parts of the fugue where new material is heard, based on the subject—a stretto, when the fugue's subject "overlaps" itself in different voices, or a recapitulation. A popular compositional technique in the Baroque era, the fugue was fundamental in showing mastery of harmony and tonality as it presented counterpoint.
Johann Pachelbel was a German composer, organist, and teacher who brought the south German organ schools to their 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.
The Toccata and Fugue in D minor, BWV 565, is a composition for organ by, according to the oldest sources, German composer Johann Sebastian Bach and is one of the most widely recognisable works in the organ repertoire. Although the date of its origin is unknown, scholars have suggested between 1704 and the 1750s. The piece opens with a toccata section followed by a fugue that ends in a coda, and is largely typical of the north German organ school of the Baroque era.
Karl Richter was a German conductor, choirmaster, organist, and harpsichordist.
A prelude and fugue is a musical form generally consisting of two movements in the same key for solo keyboard. In classical music, the combination of prelude and fugue is one with a long history. Many composers have written works of this kind. The use of this format is generally inspired by Johann Sebastian Bach's two books of preludes and fugues — The Well-Tempered Clavier — completed in 1722 and 1742 respectively. Bach, however, was not the first to compose such a set: Johann Caspar Ferdinand Fischer wrote a 20-key cycle in his 1702 work Ariadne musica.
D minor is a minor scale based on D, consisting of the pitches D, E, F, G, A, B♭, and C. Its key signature has one flat. Its relative major is F major and its parallel major is D major.
The Eight Short Preludes and Fugues, BWV 553–560, are a collection of works for keyboard and pedal formerly attributed to Johann Sebastian Bach. They are now believed to have been composed by one of Bach's pupils, possibly Johann Tobias Krebs or his son Johann Ludwig Krebs, or by the Bohemian composer Johann Caspar Ferdinand Fischer.
Toccata, Adagio, and Fugue in C major is an organ composition by Johann Sebastian Bach. As is the case with most other organ works by Bach, the autograph score does not survive. The earliest manuscript copies were probably made in 1719–1727. The title of the piece in these copies is given, as expected of organ literature of the time, simply as Toccata in C major. The piece is an early work, probably composed in the mid-to-late Weimar years, i.e. 1710–1717. It shares some similarities with other toccatas composed around the same time, such as BWV 538, BWV 540, and others: all show the influence of concerto style and form.

Johann Sebastian Bach was a German composer and musician of the late Baroque period. He is known for his prolific authorship of music across a variety of instruments and forms, including; orchestral music such as the Brandenburg Concertos; solo instrumental works such as the cello suites and sonatas and partitas for solo violin; keyboard works such as the Goldberg Variations and The Well-Tempered Clavier; organ works such as the Schubler Chorales and the Toccata and Fugue in D minor; and choral works such as the St Matthew Passion and the Mass in B minor. Since the 19th-century Bach Revival, he has been generally regarded as one of the greatest composers in the history of Western music.
Prelude and Fugue in A minor, BWV 543 is a piece of organ music written by Johann Sebastian Bach sometime around his years as court organist to the Duke of Saxe-Weimar (1708–1713).
The keyboard concertos, BWV 1052–1065, are concertos for harpsichord, strings and continuo by Johann Sebastian Bach. There are seven complete concertos for a single harpsichord, three concertos for two harpsichords, two concertos for three harpsichords, and one concerto for four harpsichords. Two other concertos include solo harpsichord parts: the concerto BWV 1044, which has solo parts for harpsichord, violin and flute, and Brandenburg Concerto No. 5 in D major, with the same scoring. In addition, there is a nine-bar concerto fragment for harpsichord which adds an oboe to the strings and continuo.
The six sonatas for violin and obbligato harpsichord BWV 1014–1019 by Johann Sebastian Bach are works in trio sonata form, with the two upper parts in the harpsichord and violin over a bass line supplied by the harpsichord and an optional viola da gamba. Unlike baroque sonatas for solo instrument and continuo, where the realisation of the figured bass was left to the discretion of the performer, the keyboard part in the sonatas was almost entirely specified by Bach. They were probably mostly composed during Bach's final years in Cöthen between 1720 and 1723, before he moved to Leipzig. The extant sources for the collection span the whole of Bach's period in Leipzig, during which time he continued to make changes to the score.
Prelude and Fugue in E minor, BWV 548 is a piece of organ music written by Johann Sebastian Bach sometime between 1727 and 1736, during his time in Leipzig. The work is sometimes called "The Wedge" due to the chromatic outward motion of the fugue theme. Unlike most other organ preludes and fugues of Bach, the autograph fair copy of the score survives, though the handwriting changes twenty two measures into the fugue to the hand of Johann Peter Kellner, a likely pupil and acquaintance of Bach who played an important role in the copying of his manuscripts. Because of the work's immense scope, it has been referred to as "a two-movement symphony" for the organ.
The organ sonatas, BWV 525–530 by Johann Sebastian Bach are a collection of six sonatas in trio sonata form. Each of the sonatas has three movements, with three independent parts in the two manuals and obbligato pedal. The collection was put together in Leipzig in the late 1720s and contained reworkings of prior compositions by Bach from earlier cantatas, organ works and chamber music as well as some newly composed movements. The sixth sonata, BWV 530, is the only one for which all three movements were specially composed for the collection. When played on an organ, the second manual part is often played an octave lower on the keyboard with appropriate registration. Commentators have suggested that the collection might partly have been intended for private study to perfect organ technique, some pointing out that its compass allows it to be played on a pedal clavichord. The collection of sonatas is generally regarded as one of Bach's masterpieces for organ. The sonatas are also considered to be amongst his most difficult compositions for the instrument.
The organ concertos of Johann Sebastian Bach are solo works for organ, transcribed and reworked from instrumental concertos originally composed by Antonio Vivaldi and the musically talented Prince Johann Ernst of Saxe-Weimar. While there is no doubt about the authenticity of BWV 592–596, the sixth concerto BWV 597 is now probably considered to be spurious. Composed during Bach's second period at the court in Weimar (1708–1717), the concertos can be dated more precisely to 1713–1714.
