This section describes the importance of scared music in the church and culture during the middle ages. The church began to organize music into liturgy. The melodies of this music became known as Gregorian chants. The Gregorian chants began to expand when it was set to text into three main classes. The classes are syllabic, neumatic, and melismatic. The chants were recited in mass which lead to its progression and preservation. As voices were added to the Gregorian melody polyphonic music like organum was produced. The result of organum was that it was the genre in which composers first experimented with rhythmic ideas and conceived a polyphonic style with hollow harmonies.
