In the eighth movement of a mass by this composer, violins play a sudden dissonant tremolo before the basses enter singing “C, B-flat, C [pause] A” on the lyric “dies illa.” A “Sanctus” by this composer is accompanied by perpetuum mobile sextuplets in the violas, which the organ plays in its reduced orchestration. This composer’s vocal writing is characterized by mixed meter, (15[1])monophony, and modality, as in his mass Cum Jubilo. The motet “Ubi (-5[1])Caritas” is one of this perfectionist composer’s 14 works. Durand published this composer’s most famous piece, which was commissioned by the (*) Vichy (10[1])government and based on (10[1])Gregorian chant. Like a more popular precursor, that D minor piece ends with the “In Paradisum” and omits the “Sequenza.” For 10 points, what composer’s Requiem is often compared to that of (10[1])his countryman Gabriel (10[1])Fauré?
