Opening chords use the Salicional 8' and Salicional Celeste 8' with Swell to Swell 4' coupling.
The opening of the main theme is introduced by the Oboe 4', Nachthorn 4', Swell Unison Off, and Swell to Swell 16' couplers. It is continued by the Great Bourdon 8', then played with the accompaniment on the Choir Prestant 4' stop with Choir Unison Off, Choir to Choir 16' couplers. Then it's back to the Oboe.
The loud middle section employs the addition of the Swell Trompette 8' (Swell Unison Off, Swell to Swell 16') and a fairly full pedal division including the Bombarde 16' and the Resultant 32' (no mixtures).
