The role of masks during the Fez Festival of World Sacred Music in Morocco is significant, as they represent different cultural and spiritual traditions from various global ethnic communities. Masks are often used in performances to convey emotions, symbolize characters, or embody spiritual representations during sacred music presentations. They enhance the visual impact of the performances, encouraging audiences to engage deeply with the music and the stories being shared. The use of masks serves to connect the audience with the diverse cultures represented at the festival, fostering intercultural dialogue and promoting appreciation for the rich tapestry of world music traditions.
