This work comes from a suite of pieces and they are dedicated to Langlais' teacher, Marcel Dupre.
It is a simple piece calling for two 16 foots and an 8 foot on the manuals with a 4 foot on the pedal playing the cantus firmus of the kyrie. The 16 foots come from the using Dulciana and Gamba 8 foot with the Suboctave coupler. The pedal Super Octave provides the 4 foot.
