sentences:  The "Credo", typically the longest section of any mass setting, uses 40 voices in many places, but intersperses many passages for smaller units.Sections of the mass which normally have a fuller, more exuberant musical setting, such as the "Et Resurrexit" (and He was resurrected) have all 40 voices, while those which more sedate or sorrowful, for example the "Crucifixus", have the smallest groupings (in this case, only eight voices of one choir sing).The closing "Agnus Dei", with 60 voices in five groups of 12, has more independent parts than any other polyphonic composition of the Renaissance.
