The “Agnus Dei” for seven-part mixed choir op. 40 by Kaiser-Lindemann is formatwise similar to the “Tre pezzi sacri“ op. 31. Both compositions therefor work well for a combined performance with their mixed choir formation. This orchestration showes the same instrumental ensemble as the Requiem by Wolfgang Amadeus Mozart. So this opens up the possibility of combining both pieces in one performance as well.

Alternative instrumental settings are published for

1. Organ op. 41
2. Orchestra op. 41a
