Gioachino Rossini's Petite messe solennelle (Little solemn mass) was written in 1863, possibly at the request of Count Alexis Pillet-Will for his wife Louise to whom it is dedicated. The composer, who had retired from composing operas more than 30 years before, described it as "the last of my péchés de vieillesse" (sins of old age). The mass was first performed on 14 March 1864 at the couple's new residence in Paris, the hôtel of Louise, comtesse de Pillet-Will.
