The Six Chorales of Various Kinds, also known as Schübler Chorales, are six pieces composed by Johann Sebastian Bach and published around 1748. The informal title, 'Schübler', derives from the name of the original engraver of the collection. The six pieces are written for a single organ with two manuals and a pedal, and are transcribed from sections of Bach's cantatas (with BWV 646 assumed to derive from one of the lost cantatas). It is understood that this set of pieces was conceived as an approachable version of the cantatas (which were largely unpublished during Bach's lifetime).
