The document discusses different types of medieval era compositions including: 1) Lauda - simple Italian devotional songs composed for private use with a verse/refrain format. 2) Church dramas - biblical stories set to monophonic melodies for soloists and chorus, often associated with liturgical feasts. 3) Monophonic compositions were divided into four periods including St. Martial known for two-voiced organum styles, Notre Dame known for liturgical works by Léonin and Pérotin, and Ars Antiqua which continued with rhythmically active upper parts set to French texts over chant-based lower parts.
