What is "salon music"

Salon music was a popular music genre in Europe during the 19th century. It was usually written for solo piano in the romantic style, and often performed by the composer at events known as "Salons". Salon compositions are usually fairly short and often focus on virtuoso pianistic display or emotional expression of a sentimental character. Common subgenres of salon music are the operatic paraphrase or fantasia, in which multiple themes from a popular opera are the basis of the composition, and the musical character-piece, which portrays in music a particular situation or narrative.
