For his anthology Caecilia – 253 Preludes for Organ or Harmonium, editor August Reinhard (1831–1912) noticeably drew on the achievements of the preceding generation. Pride of place was given to August Friedrich Hesse and Johann Christian Heinrich Rinck. Most of the preludes – ranging from very easy to medium-level difficulty – can be used in a variety of ways in the religious service, since they are not based on one specific chorale melody. The collection also displays its eminent usefulness for performers through the disposition of the keys.
