Is gregorian chant devil work or music?

Gregorian chant is not the devil's music, but rather a sacred form of music that has been used in Christian worship for centuries. It is a type of monophonic vocal music that is sung by a choir of monks or nuns, and is characterized by its simple melodies, slow tempo, and use of Latin lyrics. Gregorian chant is considered to be a form of sacred music because of its religious nature and its use in worship, and it is highly respected and venerated within Christian tradition.
