I used to play this piece during the reception of the communion, because it has this soothing character and always made me feel 'at peace' with the world.
...And, of course, because one could adapt it for the evening as well as the morning mass by either playing the reprise of the first part or directly going for the second part. ;-)
I first wanted to record it on the Doesburg, which should be fitting for Karg-Elert, but the beautiful Flutes of the Caen convinced me otherwise.
On real organs one often has to be very creative to find just the right pedal registration for this piece - Mr. Karg-Elert wrote "either 4' or a noble 8' solo stop" for the pedal.
The Caen offers beautiful stops for this, if used a bit creatively. In this piece, I made use of the I 4' - P coupler and combined the beautiful Flute harmonique from the G.O. as 4' stop with the 4' Pedal Flute.
Récit: Voix céleste, Gambe (+ Flûte traver. for the final part)
Positif: Salicional, Cor de nuit, Flûte douce
G.O. (4' coupled to P): Flûte harmonique
only III-P for the final part
