The Middle Ages

The medieval era (476 AD to 1400 AD) started with the introduction of chanting into Roman Catholic Church services. Western Music then
started becoming more of an art form with the advances in music notation. The only European Medieval repertory that survives from before about 800 is the monophonic liturgical plainsong of the Roman Catholic Church, the central tradition of which was called Gregorian chant. Alongside these traditions of sacred and church music there existed a vibrant tradition of secular song. Examples of composers from this period are Léonin, Pérotin and Guillaume de Machaut. From the Renaissance music era, much of the surviving music of 14th-century Europe is secular. By the middle of the 15th century, composers and singers used a smooth polyphony for sacred musical compositions. Prominent composers from this era are Guillaume Dufay, Giovanni Pierluigi da Palestrina, Thomas Morley, and Orlande de Lassus.
