Early polyphony emerged in Western music during the medieval period, around the 9th century. It involved the simultaneous singing of two or more independent melodic lines. Initially, early polyphony was primarily found in sacred music, particularly in Gregorian chant. Over time, composers began to experiment with adding additional voices and creating more complex harmonies, leading to the development of intricate polyphonic compositions.
