The sixth part of Masaaki Suzuki's highly acclaimed complete edition of Johann Sebastian Bach's organ works presents the first eleven pieces from a manuscript which has since become known as the "Leipzig Chorale". This collection, which was written around 1739, is unusual in that it contains no new compositions, but rather arrangements of organ chorales from the years 1708-17, when Bach lived in Weimar. The chorale arrangements are based on well-known Lutheran melodies that Bach particularly liked. They were not intended as preludes for congregational singing, but as incidental music for the communion service or as concert music. Bach devoted great care to this project, selecting the best of his organ works from his earlier creative years, and regarded it as his legacy for the future. Together with the little organ book, the "Schubler Chorales" and the third book of the "Clavier-Ubung", the Leipzig Chorales represent the high point of Bach's sacred organ music. On this recording, Masaaki Suzuki plays on the Arp Schnitger organ in the Martinikerk in Groningen, Netherlands, one of the largest and most famous baroque organs in Northern Europe. Arp Schnitger was the most famous organ builder in northern Germany in the 17th century, and his admirers included Buxtehude, Handel and Bach himself.
