Why are gregorian chants no longer sung?

Gregorian chants are not commonly sung today primarily because musical styles and worship practices have evolved significantly since their peak in the medieval period. The rise of polyphonic music and contemporary worship forms has shifted focus away from the monophonic, liturgical nature of Gregorian chant. Additionally, changing cultural and congregational dynamics have led many communities to favor more modern musical expressions that resonate with today's audiences. However, Gregorian chants are still performed in certain liturgical settings and by specialized choirs dedicated to preserving this historical music tradition.
