<P> 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 (for instance, the Air from Orchestral Suite No. 3, or the Wachet auf...chorale prelude) and Wendy Carlos' 1968 Switched - On Bach, which used the Moog electronic synthesiser . </P> <P> 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 on - line, with several websites exclusively dedicated to him . </P> <P> In his own time, Bach's reputation equalled those 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 his hometown of 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 . </P> <P> 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 . </P>
