Detailed Study Notes on Organum and Polyphony in Medieval Music

The session focuses on topics of organum and polyphony in medieval music.
Key elements include the discussion on composers, compositions, and resources for recordings.

To access class recordings:
- Navigate to the course interface, select Discussions where all tracks are listed.

Organum includes techniques of singing and composition, focusing on parallel organum.
- Discussed types include two-voice and four-voice organum.
- Inherent parallels can be both beneficial and problematic in voice leading.

Students were questioned regarding problems associated with musical parallels:
- Presented various viewpoints on concerns about parallel harmonies.
- Instructor communicated that no inherent fault exists in using parallels.
- Cited prominent figures like Hans Zimmer as proponents of effective paralleling in composing for dramatic scenes.
- Notable influences of composers such as Beethoven and Debussy illustrate parallels' acceptance in significant works.

Vox Principalis: The principal voice of the original plainchant.
- Polyphony in Catholic Church emerges from guiding the original chant melody and adding a second part.
- Instant polyphony can be created by layering the vox organalis over the vox principalis.

Vox Organalis: Voice of harmony in organum.
- Harmonization changes from the principal melody to typically being added as an upper part in polyphony.
- Emphasis on the arrangement where the harmony is above the melody, differing from today's choral standards.

Preference for certain musical intervals in polyphony:
- Perfect Intervals: Unison, perfect fourths, fifths, and octaves are prioritized.
- Imperfect Intervals: Thirds and sixths also included, but considered secondary to perfect intervals.

First example analyzed is a well-known melismatic piece, involving the text "Lord have mercy".
- Tropes: Introducing words into pre-existing chants indicated a fusion of old and new.
Emphasis on the anonymity of most chant composers, predominantly monks, while acknowledging notable exceptions like Hildegard von Bingen.

The term Tenor derives from Latin tenere, meaning to hold, typically referring to the lower part holding the plainchant.
Often in historical polyphony, the voice beneath (tenor) serves as a foundation for the upper voices in harmony.

Contemporary transcriptions differ significantly from the original medieval notations, which were less structured.
- The concept of Enchippet used to guide singers in their chant references, originating as an organizational method dating back to the medieval period.

With the rise of polyphony, there was a necessity for note values (durations) to ensure coherent harmony among singers.
- The development of meter and structured note durations enabled organized singing in polyphony and avoided discordant intervals like tritones.

Notre Dame Cathedral: An architectural marvel and cultural site in Paris.
The cathedral became a hub for writing polyphonic music known as the Notre Dame School.
- Prominent medieval composers, specifically Leoninus, pioneered polyphony here.
- He created two distinct styles: melismatic organum (free) and measured organum (note-to-note).

Discant Organum: Notation focusing on one note per syllable in contrast to free, melismatic styles.
- Examined both Leoninus and Perotin's contributions to the development of early polyphonic music, differentiating between two and four-voice polyphony.

Emphasized the experience of medieval citizens encountering polyphony in worship, likely eliciting awe due to the shift from monophonic chanting.
- The performance involved not just the choir but congregational participation, connecting believers with a mystical notion that includes historical figures and divine presence in worship.

The hierarchy within the church, from the Pope down to local bishops levels, shaped the musical practices and educational methods in cathedrals like Notre Dame.

Further exploration of polyphony and its development will continue in subsequent classes, with an emphasis on the historical significance and changing practices of music in worship and its composite structure over time.
