Saint-Brice Church in Ay welcomes a classical music festival every year. Organized for 25 years, it pays tribute to Baroque music. The church's pipe organ in French Baroque style, dating from 1749, still resonates on this occasion. It was built by the Reims carpenter Jean Labègue and was raised and modified in 1898. Over the years, the festival has become an unmissable event in the city, with regional resonance.
