A new interpretation of the Age of Enlightenment through the lens of music, institutions, and markets   The birth of public concerts changed Europe’s cultural landscape by introducing sacred music to secular spaces. The Concert spirituel in Paris is a landmark in this Enlightenment transition: the first long-lasting concert series, it began in 1725 with performances that mostly featured sacred music composed for the royal chapel in Versailles. By the time the Concert ended, in 1790, it was presenting a variety of musical genres, and its sacred repertoire had declined precipitously. The Concert had evolved from an institution dependent on the church calendar and the court into a business in a competitive market.   Andrei Pesic explores the dynamics of secularization during the Enlightenment, including the unintended consequences of linking music to commerce, social hierarchy, and religious practices. He reveals the role of public concerts in a burgeoning marketplace for entertainment—and the expansion of secular customs and diminishment of religious constraints—in places as varied as Paris, Berlin, and Haiti. Andrei Pesic is assistant professor of French and Italian at Stanford University.
