In comparison with the first two organ symphonies, the Organ Symphony No. 3 or Symphonie Dorienne is more intimate and contemplative, its musical language being more subdued and harmonically developed. It is a modern-classical composition that consists of four movements. The 1st one is a solemn and moderately fast prelude based on one flowing theme. The 2nd one is a fast gargoylesque scherzo with a singing pastoral middle section, dominated by the Cornets. The 3rd one is a slow and rather sad movement in sonata form with two contrasting themes (a singing main theme and a choral-like one). The 4th and final movement is characterised by the alternation of a slow and solemn episode and a fast twinkling toccata-like theme, that are both further developed. At the end the toccata-like theme returns one last time in a majestic way, and thereafter a moving solo of the Flûte harmonique (joined by the Montre) brings the symphony to its calm conclusion. 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). In 2016 I have revised the piece, checking every registration indication and every bar and I can assure now that the piece is entirely playable and that it will sound great if you follow my registration indications. The recording (digital performance in Sibelius 5 with Garritan Personal Orchestra, not Hauptwerk, of the former version of 2011 !) gives, besides the registration indications, a scant indication of the sound I want.
