The organ book contains a treasure of works from all eras, among them pieces which are little known and hard to find that will expand and enrich the repertoire of every organist. The works of easier and medium difficulty will be welcomed by beginning organ ists, but also more experienced players will discover little-known gems of organ music. In addition to the main volume, a second volume includes intonations for the acclamation before the Gospel and processional music; a CD is also available.
