During the Medieval Era (roughly from the 5th to the 15th century), the Christian Church—especially the Roman Catholic Church—had a powerful influence on the culture, education, and music of Europe.• Most of the music during this time was religious or sacred in nature.• The Church developed and preserved Gregorian Chant, a form of plainchant used in masses and prayers.• Monasteries and churches were the centers of learning and music, and many composers were priests or monks.
