Giovanni Pierluigi da Palestrina
Giovanni Pierluigi da Palestrina ( 1525 – 2 February 1594) was an Italian Renaissance composer of sacred music and the best-known 16th-century representative of the Roman School of musical composition. He had a lasting influence on the development of church music, and his work is considered as the culmination of Renaissance polyphony.
O magnum mysterium (Palestrina)
O magnum mysterium is a six-part motet by Giovanni Pierluigi da Palestrina, based on the responsorial chant of the same name, and was written for the celebration of Christmas. The piece is intended to express the joy and awe that was felt by the shepherds as they celebrated and worshiped the Christ-child in the manger on Christmas Eve. Palestrina took the text for this piece from the first half of the third and fourth Responsories of Matins on Christmas Day. The text has been set many times by numerous composers, such as Palestrina, Poulenc, Lauridsen, and Morales.
