The Composition      While the Rex tremendae majestatus is one of the Requiem’s shortest movements, I've included a particularly wide range of dynamic expression in its two minutes.

The movement begins with a timpani roll followed by full orchestra and chorus.  Then, starting with lyrical strings, the dynamics gradually decrease, from a woodwinds ensemble, to a solo English horn, and finally to the boys alone, stating the movement's brief theme. Then the dynamics start to increase again, as four successively larger groups of strings join the orchestra. When the strings are at full strength, a cymbal crash announces the return of the full orchestra and chorus for the finale.  But in the final measures, the boys, supported by the men, are left to quietly finish the movement.   

Rex tremendae majestatus is scored for SATB chorus and boys’ choir; strings (24 violins, 8 violas, 8 cellos, 9 double bases;)  brass (6 French horns, 6 trumpets;) woodwinds (3 flutes, 3 clarinets, 2 oboes, 2 bassoons, 1 English horn)  and timpani.
