Reception of Johann Sebastian Bach's music
In the 18th century, the appreciation of Johann Sebastian Bach's music was mostly limited to distinguished connoisseurs. The 19th century started with publication of the first biography of the composer and ended with the completion of the publication of all of Bach's known works by the Bach Gesellschaft. The "Bach Revival" started with Felix Mendelssohn's performance of the St Matthew Passion in 1829. Soon after that performance, Bach started to become regarded as one of the greatest composers of all time, if not the greatest, a reputation he has retained ever since. A new extensive Bach biography was published in the second half of the 19th century.
In the 20th century, Bach's music was widely performed and recorded, while the Neue Bachgesellschaft, among others, published research on the composer. Modern adaptations of Bach's music contributed greatly to his popularisation in the second half of the 20th century. Among these were the Swingle Singers' versions of Bach pieces and Wendy Carlos' 1968 Switched-On Bach, which used the Moog electronic synthesiser.
By the end of the 20th century, more classical performers were gradually moving away from the performance style and instrumentation that were established in the romantic era: they started to perform Bach's music on period instruments of the baroque era, studied and practised playing techniques and tempi as established in his time, and reduced the size of instrumental ensembles and choirs to what he would have employed. The BACH motif, used by the composer in his own compositions, was used in dozens of tributes to the composer from the 19th century to the 21st. In the 21st century, the complete extant output of the composer became available online, with several websites exclusively dedicated to him.
18th century
In his own time, Bach's reputation equalled that of Telemann, Graun and Handel. During his life, Bach received public recognition, such as the title of court composer by Augustus III of Poland and the appreciation he was shown by Frederick the Great and Hermann Karl von Keyserling. Such highly placed appreciation contrasted with the humiliations he had to cope with, for instance in Leipzig. Also in the contemporary press, Bach had his detractors, such as Johann Adolf Scheibe, suggesting he write less complex music, and his supporters, such as Johann Mattheson and Lorenz Christoph Mizler.After his death, Bach's reputation as a composer at first declined: his work was regarded as old-fashioned compared to the emerging galant style. Initially, he was remembered more as a virtuoso player of the organ and as a teacher. The bulk of the music that had been printed during the composer's lifetime, at least the part that was remembered, was for the organ and the harpsichord. Thus, his reputation as a composer was initially mostly limited to his keyboard music, and that even fairly limited to its value in music education.
Bach's surviving family members, who inherited a large part of his manuscripts, were not all equally concerned with preserving them, leading to considerable losses. Carl Philipp Emanuel, his second eldest son, was most active in safeguarding his father's legacy: he co-authored his father's obituary, contributed to the publication of his four-part chorales, staged some of his works, and the bulk of previously unpublished works of his father were preserved with his help. Wilhelm Friedemann, the eldest son, performed several of his father's cantatas in Halle but after becoming unemployed sold part of the large collection of his father's works he owned. Several students of the old master, such as his son-in-law Johann Christoph Altnickol, Johann Friedrich Agricola, Johann Kirnberger and Johann Ludwig Krebs, contributed to the dissemination of his legacy. The early devotees were not all musicians; for example, in Berlin, Daniel Itzig, a high official of Frederick the Great's court, venerated Bach. His eldest daughters took lessons from Kirnberger, and their younger sister Sara from Wilhelm Friedemann Bach, who was in Berlin from 1774 to 1784. Sara Itzig became an avid collector of works by Johann Sebastian Bach and his sons.
While in Leipzig, performances of Bach's church music were limited to some of his motets, and under cantor Doles some of his Passions. A new generation of Bach aficionados emerged: they studiously collected and copied his music, including some of his large-scale works such as the Mass in B minor and performed it privately. One such connoisseur was Gottfried van Swieten, a high-ranking Austrian official who was instrumental in passing Bach's legacy on to the composers of the Viennese school. Haydn owned manuscript copies of the Well-Tempered Clavier and the Mass in B minor and was influenced by Bach's music. Mozart owned a copy of one of Bach's motets, transcribed some of his instrumental works, and wrote contrapuntal music influenced by his style. Beethoven played the entire Well-Tempered Clavier by the time he was 11 and described Bach as Urvater der Harmonie.
In the composer's lifetime
The earliest known reference to Johann Sebastian Bach in print is a compliment by Mattheson:Bach's cousin Johann Gottfried Walther published a in 1732: in the publication he qualified Bach's keyboard compositions as outstanding. In 1737, Scheibe published an unfavourable criticism, without naming his subject:"Mr. —" being identified as Bach, and the "person with whom he can dispute the palm" as Georg Frideric Handel, Johann Abraham Birnbaum, a professor of Leipzig University, published a defence of the "royal Polish and Saxonian electoral court composer and chapel master Mr. Johann Sebastian Bach" :Agreeing with Birnbaum's views, Mizler republished his Unpartheyische Anmerckungen a few months later.Second half of the 18th century
From 1760 onwards a small group of ardent supporters became active in Berlin, keen to preserve his reputation and promulgate his oeuvre. The group centred around his son Carl Philipp Emanuel Bach, who in 1738 at the age of 24 had been appointed court harpsichordist at Potsdam to Frederick the Great, then crown prince before his accession to the throne in 1740. C.P.E. Bach remained in Berlin until 1768, when he was appointed Kapellmeister in Hamburg in succession to Georg Philipp Telemann. Other prominent members of the group included Bach's former pupils Johann Friedrich Agricola, court composer, first director of the Royal Opera House in Berlin and collaborator with Emanuel on Bach's obituary, and more significantly Johann Philipp Kirnberger.Kirnberger became Kapellmeister to the court in 1758 and music teacher of Frederick's niece, Anna Amalia. Not only did Kirnberger build up a large collection of Bach's manuscripts in the Amalien-Bibliothek, but with Friedrich Wilhelm Marpurg he promoted Bach's compositions through theoretical texts, concentrating in particular on counterpoint with a detailed analysis of Bach's methods. The first of the two volumes of Marpurg's Treatise on fugue cites the opening segment of the six-part fugal chorale prelude Aus tiefer Noth BWV 686 as one of its examples. Kirnberger produced his own extensive tract on composition Die Kunst des reinen Satzes in der Musik, twenty years later, between 1771 and 1779. In his treatise Marpurg had adopted some of the musical theories on the fundamental bass of Jean-Philippe Rameau from his Treatise on Harmony in explaining Bach's fugal compositions, an approach which Kirnberger rejected in his tract:
This led to an acrimonious dispute in which both claimed to speak with Bach's authority. When Marpurg made the tactical error of suggesting that, "His famous son in Hamburg ought to know something about this, too", Kirnberger responded in the introduction to the second volume of his tract:
Through Bach's pupils and family, copies of his keyboard works were disseminated and studied throughout Germany; the diplomat Baron van Swieten, Austrian envoy to the Prussian court from 1770 to 1777 and afterwards patron of Mozart, Haydn and Beethoven, was responsible for relaying copies from Berlin to Vienna. The reception of the works was mixed, partly because of their technical difficulty: composers like Mozart, Beethoven and Rust embraced these compositions, particularly The Well-Tempered Clavier; but, as Johann Adam Hiller reported in 1768, many amateur musicians found them too hard.
Twenty-one prints of the original 1739 edition of Clavier-Übung III survive today. Because of its high price, this edition did not sell well: even 25 years later in 1764, C.P.E. Bach was still trying to dispose of copies. Because of changes in popular tastes after Bach's death, the publisher Johann Gottlob Immanuel Breitkopf, son of Bernhard Christoph Breitkopf, did not consider it economically viable to prepare new printed editions of Bach's works; instead he retained a master copy of Clavier-Übung III in his large library of original scores from which handwritten copies could be ordered from 1763 onwards. A similar service was provided by the musical publishers Johann Christoph Westphal in Hamburg and Johann Carl Friedrich Rellstab in Berlin.
Before 1800, there are very few reports of performances of Bach's works in England or of manuscript copies of his work. In 1770, Charles Burney, the musicologist and friend of Samuel Johnson and James Boswell, had made a tour of France and Italy. On his return in 1771 he published a report on his tour in The Present State of Music in France and Italy. Later that year in a letter to Christoph Daniel Ebeling, the music critic engaged in translating this work into German, Burney made one of his first references to Bach:
It was, however, only in the following year, during his tour of Germany and the Low Countries, that Burney received a copy of the first book of The Well-Tempered Clavier from C. P. E. Bach in Hamburg; according to his own reports, he was only to become familiar with its contents over thirty years later. He reported on his German tour in The Present State of Music in Germany, the Netherlands and United Provinces in 1773. The book contains the first English account of Bach's work and reflects the views commonly held at the time in England. Burney compared the learned style of Bach unfavourably with that of his son, whom he had visited:
Burney summarised the musical contributions of J.S. Bach as follows:

As it is known that at the time Burney knew hardly any of Bach's compositions, it appears that his opinions of Bach came second-hand: the first sentence was almost certainly lifted directly from the French translation of Marpurg's Treatise on fugue, to which he had referred earlier in the book for biographical details; and in 1771 he had acquired Scheibe's writings through Ebeling. In Germany Burney's book was not well received, infuriating even his friend Ebeling: in a passage that he changed in later editions, he had repeated without attribution comments from a letter of Louis Devisme, British plenipotentiary in Munich, that, "if innate genius exists, Germany is certainly not the seat of it; though it must be allowed, to be that of perseverance and application." Once aware of the offence this might cause to Germans, Burney had marked with pencil the offending passages in the copy of his daughter Fanny Burney, when in 1786 she became lady-in-waiting to Queen Charlotte. Later that year, to Fanny's horror, the Queen requested that Fanny show her copy to her daughter Princess Elizabeth. The book was viewed by both King George III and Queen Charlotte, who accepted Fanny's hastily invented explanations of the markings; she similarly managed to excuse herself when Princess Elizabeth later read all the marked passages assuming them to be Fanny's favourites.
Johann Nikolaus Forkel, from 1778 the director of music in the University of Göttingen, was another promoter and collector of Bach's music. An active correspondent with both of Bach's sons in Berlin, he published the first detailed biography of Bach in 1802, Bach: On Johann Sebastian Bach's Life, Art and Works: For Patriotic Admirers of True Musical Art, including an appreciation of Bach's keyboard and organ music and ending with the injunction, "This man, the greatest orator-poet that ever addressed the world in the language of music, was a German! Let Germany be proud of him!
Yes, proud of him, but worthy of him too!" In 1779, Forkel published a review of Burney's General History of Music in which he criticized Burney for dismissing German composers as "dwarves or musical ogres" because "they did not skip and dance before his eyes in a dainty manner"; instead he suggested it was more appropriate to view them as "giants".
Among his criticisms of Bach in the 1730s, Scheibe had written, "We know of composers who see it as an honour to be able to compose incomprehensible and unnatural music. They pile up musical figures. They make unusual embellishments.... Are these not truly musical Goths!" Until the 1780s, the use of the word "gothic" in music was pejorative. In his entry for "harmony" in the influential Dictionnaire de Musique, Jean-Jacques Rousseau, a fierce critic of Rameau, described counterpoint as a "gothic and barbaric invention", the antithesis of the melodic galante style. In 1772, Johann Wolfgang von Goethe gave a fundamentally different view of "gothic" art that would achieve widespread acceptance during the classical-romantic movement. In his celebrated essay on the cathedral in Strasbourg, where he was a student, Goethe was one of the first writers to connect gothic art with the sublime:
In 1782, Johann Friedrich Reichardt, since 1775 the successor to Agricola as Capellmeister in the court of Frederic the Great, quoted this passage from Goethe in the Musicalisches Kunstmagazin to describe his personal reactions to the instrumental fugues of Bach and Handel. He prefaced his eulogy with a description of Bach as the greatest counterpuntalist of his age:
The unfavourable comparison to Handel was removed in a later reprinting in 1796, following adverse anonymous remarks in the Allgemeine Deutsche Bibliothek. Reichardt's comparison between Bach's music and the Gothic cathedral would often be repeated by composers and music critics. His student, the writer, composer and music critic E.T.A. Hoffmann, saw in Bach's music "the bold and wonderful, romantic cathedral with all its fantastic embellishments, which, artistically swept up into a whole, proudly and magnificently rise in the air." Hoffmann wrote of the sublime in Bach's music—the "infinite spiritual realm" in Bach's "mystical rules of counterpoint".
Another musician in C.P.E. Bach's circle was his friend Carl Friedrich Christian Fasch, son of the violinist and composer Johann Friedrich Fasch, who, on the death of Kuhnau in 1722, had turned down the post, later awarded to Bach, of kantor at the Thomaskirche, where he himself had been trained. From 1756 Carl Fasch shared the role of harpsichord accompanist to Frederick the Great at Potsdam with C.P.E. Bach. He briefly succeeded Agricola as director of the Royal Opera in 1774 for two years. In 1786. the year of Frederick the Great's death, Hiller organised a monumental performance in Italian of Handel's Messiah in a Berlin cathedral, recreating the scale of the 1784 London Handel Commemoration described in Burney's detailed account of 1785. Three years later in 1789, Fasch started an informal group in Berlin, formed from singing students and music lovers, that met for rehearsals in private homes. In 1791, with the introduction of a "presence book", it became officially known as the Sing-Akademie zu Berlin and two years later was granted its own rehearsal room in the Royal Academy of Arts in Berlin. As a composer, Fasch had learnt the old methods of counterpoint from Kirnberger and, like the Academy of Ancient Music in London, his initial purpose in founding the Sing-Akademie was to revive interest in neglected and rarely performed sacred vocal music, particularly that of J.S. Bach, Graun and Handel. The society subsequently built up an extensive library of baroque music of all types, including instrumental music.
Burney was aware of George III's preference for Handel when in 1785 he wrote in his account of the 1784 Handel Commemoration that "in his full, masterly and excellent organ-fugues, upon the most natural and pleasing subjects, he has surpassed Frescobaldi, and even Sebastian Bach, and others of his countrymen, the most renowned for abilities in this difficult and elaborate species of composition." His account was translated into German by Hiller. Writing anonymously in the Allgemeine Deutsche Bibliothek in 1788, C.P.E. Bach angrily responded that "there is nothing to be seen but partiality, and of any close acquaintance with the principal works of J.S. Bach for organ we find in Dr. Burney's writings no trace." Undeterred by such comments in 1789, a year after C.P.E. Bach's death, Burney echoed Scheibe's earlier comparison of Bach and Handel when he wrote in his General History of Music:
File:Father-Smith-Organ-St-Paul's-1789.jpg|thumb|upright=1.6|Thanksgiving service in 1789 for the recovery of George III in St Paul's Cathedral. The Grand Organ, built by Father Smith with a case designed by Christopher Wren, can be seen in the background.
Burney reflected the English predilection for opera when he added:
Despite Burney's antipathy towards Bach prior to 1800, there was an "awakening" of interest in the music of Bach in England, spurred on by the presence of émigré musicians from Germany and Austria, trained in the musical tradition of Bach. From 1782 Queen Charlotte, a dedicated keyboard player, had as music teacher the German-born organist Charles Frederick Horn; and in the same year Augustus Frederic Christopher Kollmann was summoned by George III from the Electorate of Hanover to act as organist and schoolmaster at the Royal German Chapel at St James's Palace. It is probable that they were instrumental in acquiring for her in 1788 a bound volume from Westphal of Hamburg containing Clavier-Übung III in addition to both books of The Well-Tempered Clavier. Other German musicians moving in royal circles included Johann Christian Bach, Carl Friedrich Abel, Johann Christian Fischer, Frederick de Nicolay, Wilhelm Cramer and Johann Samuel Schroeter.
More significant for the 19th-century English Bach revival was the presence of a younger generation of German-speaking musicians in London, well versed in the theoretical writings of Kirnberger and Marpurg on counterpoint but not dependent on royal patronage; these included John Casper Heck, Charles Frederick Baumgarten and Joseph Diettenhofer. Heck in particular promoted fugues in his treatise "The Art of Playing the Harpsichord", describing them later as "a particular stile of music peculiar to the Organ than the Harpsichord"; in his biographical entry for Bach in the 1780s in the Musical Library and Universal Magazine, he gave examples of counterpoint from Bach's late period. Diettenhofer prepared A Selection of Ten Miscellaneous Fugues, including his own completion of the unfinished Contrapunctus XIV BWV 1080/19 from The Art of Fugue; prior to their publication in 1802 these were "tried at the Savoy Church, Strand before several Organists and eminent Musicians... who were highly gratified and recommended their Publication." The enthusiasm of these German musicians was shared by the organist Benjamin Cooke and his student the organist and composer John Wall Calcott. Cooke knew them through the Royal Society of Musicians and had himself published a version of The Art of Fugue. Calcott corresponded with Kollmann about the musical theories of the Bach school. In 1798, he was one of the founding members of the Concentores Society, a club with a limited membership of twelve professional musicians, dedicated to composition in counterpoint and the stile antico.
