The Organ Symphony No. 6 is a neo-romantic and rather extravert modern-classical composition, that consists of four movements. This organ symphony is dedicated to Bernhard Schneider, Organist St. Aegidien Braunschweig (Germany), who performed it in 2022 (the videos are on YouTube). The 1st movement is a solemn and fast one, based on a quite spectacular main theme with variations. The 2nd one is a slow and intimate movement that is characterized by a more developed harmony (with a lot of chromaticism). It’s in rondo form and is mainly built upon two contrasting themes (a solemn one and a singing one). The 3rd one is moderately fast and is a kind of pastoral intermezzo in which some beautiful solo registers can be used (such as the Hautbois, the Trompette and the Cornet). The 4th and final movement matches with the first movement and forms a vibrant and solemn conclusion of the symphony. Registration indications (based upon the Hauptwerk sound set of the Mutin / Cavaillé-Coll organ of the Notre Dame in Metz) are intended as a help and are mainly notated as in late French romantic organ music (Widor, Vierne). I have checked every registration indication and every bar on the pipe organ and I can assure that the piece will sound great if you follow my registration indications. The recording (digital performance in Sibelius 6 with Garritan Personal Orchestra, not Hauptwerk) gives, besides the registration indications, an idea of the sound I want.
