In previous arrangements of the cycle L’Organiste by César Franck, originally for harmonium, the notes have generally been transferred 1:1 to the various manuals and pedals of the organ. Carsten Wiebusch’s arrangement, on the other hand, aims to turn the harmonium pieces into real organ pieces. The results are pieces which, on the one hand, have a completely independent value as masterful organ miniatures and, on the other hand, can be serve as a guide for playing, registration and interpretation techniques of the great French Romantic organ world, and thus also in organ lessons.
