context_page_description: The Orgelbüchlein BWV 599−644 is a set of 45 chorale preludes for organ — one of them is given in two versions — by Johann Sebastian Bach. All but three were written between 1708 and 1717 when Bach served as organist to the ducal court in Weimar; the remainder and a short two-bar fragment came no earlier than 1726, after the composer’s appointment as cantor at the Thomasschule in Leipzig.
  The plan was for a collection of 164 settings of chorale tunes sung during the Church year so that each part of the year was represented. Although this number was not to be, the Orgelbüchlein does span the calendar and more importantly signals a maturity and new breadth in Bach’s compositional style, not only with regard to this instrument.
  Each setting takes an existing Lutheran chorale, adds a motivic accompaniment, and quite freely explores form. Many of the preludes are short and in four parts, requiring only a single keyboard and pedal, with an unadorned cantus firmus. Others involve two keyboards and pedal. These include several canons, four ornamental four-part preludes with elaborately decorated chorale lines, and one prelude in trio sonata form.
context_section_description: Bach's formal training as a musician started when he was enrolled as a chorister at the Michaelskirche in Lüneburg in 1700–1702. Manuscripts in Bach's hand recently discovered in Weimar by the Bach scholars Peter Wollny and Michael Maul show that while in Lüneburg he studied the organ with Georg Böhm, composer and organist at the Johanniskirche. The documents are hand copies made in Böhm's home in tablature format of organ compositions by Reincken, Buxtehude and others. They indicate that already at the age of 15 Bach was an accomplished organist, playing some of the most demanding repertoire of the period.
  After a brief spell in Weimar as court musician in the chapel of Johann Ernst, Duke of Saxe-Weimar, Bach was appointed as organist at St. Boniface's Church (now called the Bachkirche) in Arnstadt in the summer of 1703, having inspected and reported on the organ there earlier in the year. In 1705–1706 he was granted leave from Arnstadt to study with the organist and composer Dieterich Buxtehude in Lübeck, a pilgrimage he famously made on foot. In 1707 Bach became organist at St. Blasius' Church in Mühlhausen, before his second appointment at the court in Weimar in 1708 as concertmaster and organist, where he remained until 1717.
  During the period before his return to Weimar, Bach had composed a set of 31 chorale preludes: these were discovered independently by Christoph Wolff and Wilhelm Krunbach in the library of Yale University in the mid-1980s and first published as Das Arnstadter Orgelbuch. They form part of a larger collection of organ music compiled in the 1790s by the organist Johann Gottfried Neumeister (1756–1840) and are now referred to as the Neumeister Chorales BWV 1090–1120. These chorale preludes are all short, either in variation form or fughettas. Only a few other organ works based on chorales can be dated with any certainty to this period. These include the chorale partitas BWV 766-768 and 770, all sets of variations on a given chorale.
  During his time as organist at Arnstadt, Bach was upbraided in 1706 by the Arnstadt Consistory "for having hitherto introduced sundry curious embellishments in the chorales and mingled many strange notes in them, with the result that the congregation has been confused." The type of chorale prelude to which this refers, often called the "Arnstadt type", were used to accompany the congregation with modulating improvisatory sections between the verses: examples that are presumed to be of this form include BWV 715, 722, 726, 729, 732 and 738. The earliest surviving autograph manuscript of a chorale prelude is BWV 739, Wie schön leuchtet der Morgenstern, based on an Epiphany hymn. It dates from 1705 and possibly was prepared for Bach's visit to Lübeck.
