The cantata “Ein feste Burg ist unser Gott” was originally composed for choir, solo baritone, brass and flute ensemble. In the present version for choir, solo baritone (or mezzo-soprano) and organ, all instrumental parts are combined in the organ part. An organ registration was waived. Only the volume information serves as a guide. Each organ is individual and the organist is allowed to give free rein to his imagination in this cantata with respect to the sound design.
