Organum

Description

Organum is an early form of polyphony based on an existing plainchant. It typically features a plainchant melody with at least one added voice to enhance the harmony, creating a rich, resonant sound.

History

Organum developed during the Medieval period, around the 9th century, as an early form of polyphonic music. It evolved from the practice of adding a second voice to Gregorian chant, initially moving in parallel motion. Over time, more complex forms of organum emerged, including contrary motion and independent melodic lines, leading to the development of more intricate polyphony in the later Middle Ages.
