 None of the other dedicatees have known graves, but are commemorated on memorials to the missing.The musical forces are divided into three groups that alternate and interact with each other throughout the piece, finally fully combining at the end of the last movement.The soprano soloist and choir are accompanied by the full orchestra, the baritone and tenor soloists are accompanied by the chamber orchestra, and the boys' choir is accompanied by a small positive organ (this last group ideally being situated at some distance from the full orchestra).
