Organum

Organum is a form of early medieval music that developed around the 9th to 13th centuries, characterized by the addition of one or more melodic lines to a plainchant melody. This innovative technique allowed for harmony, where voices move together, creating a richer sound. Organum was pivotal in the evolution of Western music, as it marked the transition from monophonic plainchant to polyphony, where multiple independent melodies coexist. In literature, it reflects the broader cultural shifts of the medieval period, emphasizing creativity and the exploration of sound beyond traditional forms.
