Louis Vierne's "Messe solennelle" in C-sharp minor, Op. 16, is a significant work of sacred music from the French Romantic tradition. Composed in 1899 for choir, two organs, and orchestra, it is known for its dramatic power, rich harmonies, and contrapuntal complexity, deeply influenced by Vierne's teacher, César Franck. Despite being blind from birth, Vierne became one of the most celebrated organists and composers of his time, serving as the titular organist of Notre-Dame de Paris for 37 years.
