This sixth instalment of Masaaki Suzuki's critically acclaimed complete organ works by Johann Sebastian Bach presents the first eleven pieces from a manuscript since referred to as the Leipzig Chorales. Conceived around 1739, this collection is unusual in that it contains no new compositions, but rather 'reworkings' of organ chorales dating from the years 1708-17, when Bach was in Weimar.

The chorale arrangements are based on established Lutheran melodies that particularly appealed to Bach. They were not intended as preludes for congregational singing, but rather as music to accompany the communion service or as concert music. Bach took great care with this project, selecting the best of his organ music from earlier in his career, and saw it as his legacy for the future. Together with the Orgel-Buchlein, the Schubler Chorales and the third book of the Clavier-ubung, the Leipzig Chorales represent the pinnacle of Bach's sacred organ music.

On this recording, Masaaki Suzuki plays the Arp Schnitger organ of the Martinikerk in Groningen, the 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 seventeenth century, and his admirers included Buxtehude, Handel and Bach himself.
