Document Summary
Composers beginning to write highly ornate music with 2, 3 or 4 independent parts. Requires a system for coordinating parts rhythmically. Requires a musical notation to coordinate rhythm: music as a quadrivial science (arithmetic, geometry, astronomy, music) Hierarchies in music: consonance, dissonance, divisions of time. New systems of notation: how the medieval time approaches harmony a sort of hierarchy. Imperfect dissonances: minor seventh, major sixth, whole tone. Perfect dissonances: minor sixth, semitone, tritone (thought to be the. Devil"s chord), major seventh: poetic meter influences music meter. Leoninus and perotinus obviously has an understanding of this. Used musical notation that relied on context of notes on the pages. Grouping of notes, order of those note groupings. Missed stuff here: motet, the most important for form polyphonic vocal music in the middle ages and. This motet began as a substitute discant clausula by perotinus on the word.
