Wilhelm Friedemann Bach

Wilhelm Friedemann Bach (22 November 1710 – 1 July 1784) was a German composer, organist and harpsichordist. He was the second child and eldest son of Johann Sebastian Bach and Maria Barbara Bach. Despite his acknowledged genius as an improviser and composer, his income and employment were unstable, and he died in poverty.

Wilhelm Friedemann (hereafter Friedemann) was born in Weimar, where his father was employed as organist and chamber musician to the Duke of Saxe-Weimar. In July 1720, when Friedemann was nine, his mother Maria Barbara Bach died suddenly; Johann Sebastian Bach remarried in December 1721. J. S. Bach supervised Friedemann's musical education and career with great attention. The graded course of keyboard studies and composition that J. S. Bach provided is documented in the Clavier-Büchlein vor Wilhelm Friedemann Bach (modern spelling: Klavierbüchlein für Wilhelm Friedemann Bach), with entries by both father and son. This education also included (parts of) the French Suites, (Two-Part) Inventions, (Three-Part) Sinfonias (popularly known as "Inventions"), the first volume of The Well-Tempered Clavier, and the six Trio Sonatas for organ. At the age of 16 he went to Merseburg to learn the violin with his teacher Johann Gottlieb Graun.

In addition to his musical training, Friedemann received formal schooling beginning in Weimar. When J. S. Bach took the post of Cantor of the St. Thomas Church in Leipzig (in 1723), he enrolled Friedemann in the associated Thomasschule. (J. S. Bach—who had himself been orphaned at the age of 10—said that he took the position in Leipzig partly because of the educational opportunities it afforded his children). On graduating in 1729, Friedemann enrolled as a law student in Leipzig University, a renowned institution at the time, but later moved on to study law and mathematics at the University of Halle.

He maintained a lifelong interest in mathematics, and continued to study it privately during his first job in Dresden.

Friedemann was appointed in 1733 to the position of organist of the St. Sophia's Church at Dresden. In competing for the post he played a new version of his father's Prelude and Fugue in G Major, BWV 541. The judge described Friedemann as clearly superior to the other two candidates. He remained a renowned organist throughout his life. Among his many pupils in Dresden was Johann Gottlieb Goldberg, the keyboardist whose name is erroneously enshrined in the popular nickname given to J. S. Bach's 1742 publication, "Aria with Diverse Variations"—that is, "The Goldberg Variations." The scholar Peter Williams has discredited the story which links the work to Goldberg stating that J. S. Bach wrote the work for the Russian Ambassador Count Hermann Carl von Keyserlingk, who would ask his employee, Goldberg, to play the variations to entertain him during sleepless nights. Williams instead has argued that J. S. Bach wrote the variations to provide a display piece for Friedemann.

In 1746 Friedemann became organist of the Liebfrauenkirche at Halle.

Fk. 34 – Fugue in B-flat major: not by any Bach family member

Orchestral Suite in G Minor, BWV 1070 (possibly spurious)

Scherzo in D minor, BWV 844, attributed to both W. F. and J. S. Bach.

Wolfgang Amadeus Mozart's set of six Preludes and Fugues for string trio, K. 404a, contains five fugues transcribed from The Well-Tempered Clavier by Johann Sebastian Bach while the sixth fugue in F minor, is a transcription of one of the Eight Fugues (Falck 31) of Wilhelm Friedemann Bach. The preludes in K. 404a are Mozart's own, except for 4 (from BWV 527) and 5 (second movement from BWV 526).

Friedemann Bach is a 1941 German historical drama film directed by Traugott Müller and starring Gustaf Gründgens, Leny Marenbach and Johannes Riemann. The film depicts the life of Johann Sebastian Bach's son Wilhelm Friedemann Bach. It is based on Albert Emil Brachvogel's novel Friedemann Bach. Wilhelm Friedemann Bach is shown as a gifted son trying to escape his father's shadow.
