Marcel Proust called up his own turn-of-the-century experience to recreate the rival salons of the fictional duchesse de Guermantes and Madame Verdurin. He experienced himself his first social life in "salons" such as Mme Arman de Caillavet's one, which mixed artists and political men around Anatole France or Paul Bourget; Mme Straus' one, where the cream of the aristocracy mingled with artists and writers; or more aristocratic "salons" like Comtesse de Chevigné's, Comtesse Greffulhe's, Comtesse Jean de Castellane's, Comtesse Aimery de La Rochefoucauld's, etc. Some late 19th- and early 20th-century Paris salons were major centres for contemporary music, including those of Winnaretta Singer (the princesse de Polignac), and Élisabeth, comtesse Greffulhe. They were responsible for commissioning some of the greatest songs and chamber music works of Fauré, Debussy, Ravel and Poulenc.
