1 of 3
- Organum emerged as the earliest form of Western polyphonic music in the Middle Ages
- Developed from monophony, which consists of a single melodic line without accompaniment
- Polyphony introduced multiple independent melodic lines sounding simultaneously
- featured two voices moving in parallel motion at fixed intervals (usually perfect fourths or fifths)
- Free organum allowed for more independence between voices, with the added voice moving freely against the original melody
Evolution of Organum Styles
- Early organum primarily used in liturgical music, enhancing melodies
- Parallel organum dominated in the 9th and 10th centuries, creating a stark, hollow sound
- Free organum gained popularity in the 11th century, offering more melodic flexibility
- Gradually evolved from simple note-against-note to more complex rhythmic relationships
- Incorporation of contrary motion and oblique motion expanded the harmonic possibilities
Organum Voices
Structure and Roles of Organum Voices
- Vox principalis served as the main voice, typically carrying the original chant melody
- Vox organalis functioned as the added voice, harmonizing with the vox principalis
- Vox principalis usually placed in the lower register in early organum compositions
- Vox organalis generally moved above the vox principalis, creating higher-pitched harmonies
- Roles of voices became more fluid and interchangeable as organum developed
Development of Melismatic Organum
- introduced extended melodic passages sung to a single syllable
- Vox principalis held long, sustained notes while vox organalis performed elaborate melismas
- Created a more ornate and expressive style of organum
- Allowed for greater rhythmic complexity and melodic independence between voices
- Paved the way for the development of more intricate polyphonic forms in later periods
