Rossini's Petite messe solennelle is first performed, by twelve singers, two pianists and a harmonium player in a mansion in Paris.

Gioachino Rossini's Petite messe solennelle 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".

The pump organ or reed organ is a type of organ that uses free reeds to generate sound, with air passing over vibrating thin metal strips mounted in a frame. Types include the pressure-based harmonium, the suction reed organ, and the Indian harmonium. Historical examples include the Kunstharmonium and the American reed organ, while earlier forms include the physharmonica and the seraphine.
