Palestrina (Giovanni Pierluigi da Palestrina, c. 1525-1594) is the composer most prominently associated with the Missa Brevis in music history. A Missa Brevis (Latin for "short mass") is a concise setting of the Ordinary of the Mass. Palestrina composed several such works as part of his vast output of sacred choral music.
Palestrina was the leading composer of the Roman School during the Renaissance period and is regarded as the master of Counter-Reformation sacred polyphony. His smooth, flowing vocal lines and careful treatment of dissonance set the standard for Catholic church music for centuries.
While other composers on the list also wrote sacred music, the Missa Brevis as an examination topic in this context points to Palestrina. Monteverdi is best known for bridging the Renaissance and Baroque with works like L'Orfeo. Handel is celebrated for oratorios such as Messiah. J.S. Bach, though he composed a Missa Brevis in some forms, is primarily associated with Lutheran church music such as cantatas and the Mass in B minor.
