Music was an essential part of civic, religious, and courtly life in the Renaissance. The rich interchange of ideas in Europe, as well as political, economic, and religious events in the period 1400–1600 led to major changes in styles of composing, methods of disseminating music, new musical genres, and the development of musical instruments. The most important music of the early Renaissance was compose for use by the church—polyphonic (made up of several simultaneous melodies) masses and motets in Latin for important churches and court chapels. By the end of the sixteenth century, however, patronage was split among many areas: the Catholic Church, Protestant churches and courts, wealthy amateurs, and music printing—all were sources of income for composers.
