Plainsong Plainsong (also plainchant; Latin: cantus planus) is a body of chants used in the liturgies of the Western Church. Though the Eastern Orthodox churches and the Western Church did not split until long after the origin of plainsong, Byzantine chants are generally not classified as plainsong.
Plainsong is monophonic, consisting of a single, unaccompanied melodic line. Its rhythm is generally freer than the metered rhythm of later Western music.

Saturnalia Saturnalia was an ancient Roman festival in honor of the deity Saturn, held on the 17th of December of the Julian calendar and later expanded with festivities through to the 23rd of December. The holiday was celebrated with a sacrifice at the Temple of Saturn, in the Roman Forum, and a public banquet, followed by private gift-giving, continual partying, and a carnival atmosphere that overturned Roman social norms: gambling was permitted, and masters provided table service for their slaves.[1] The poet Catullus called it “the best of days.”
