"Concierto para Campanas" (Bell Concert) also called the Vaniloquio is an event when most of the city's thirty seven churches coordinate their ringing to music written by Llorenc Barber especially for the purpose. The concert involves more than 150 bells, rung by 130 people. The most important day for this event is 28 November, but it also occurs on the Sunday after Ash Wednesday. Three rockets fired from the center of the city signals the beginning. The city recommends that listeners climb onto a rooftop or the Pyramid or wander the streets to hear the concert best. The concert is proceeded by Aztec dance in the main square, as well as a cheese, bread and wine tasting event.
