The Organ Symphony No. 5 is a modern-classical composition. It consists of five movements. The 1st one is a moderately fast prelude, in which a solemn theme is further developed and alternated with a faster scherzo-like episode. The 2nd one is a moderately slow movement, in which a solemn main theme is alternated with two singing episodes with possibilities to use beautiful solo stops. The 3rd one is a fast scherzo with a minuet as middle section. The 4th one is a slow movement in which a quiet choral-like main theme is alternated with two other singing episodes again with possibilities to use beautiful solo stops. The 5th and final movement is a majestic toccata that must be a joy to play for a skilled organist, and to listen to. 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)? The composer has checked every registration and every bar and assures the piece is entirely playable. The recording (digital performance in Sibelius 5 with Garritan Personal Orchestra, not Hauptwerk !) gives, besides the registration indications, a scant indication of the sound the composer wants.
