The Véritables Préludes flasques is a 1912 piano composition by Erik Satie. The first of his published humoristic piano suites of the 1910s, it signified a breakthrough in his creative development and in the public perception of his music. In performance it lasts about 5 minutes.

Eric Alfred Leslie Satie, who signed his name Erik Satie after 1884, was a French composer and pianist. He was the son of a French father and a British mother. He studied at the Paris Conservatoire, but was an undistinguished student and obtained no diploma. In the 1880s he worked as a pianist in café-cabaret in Montmartre, Paris, and began composing works, mostly for solo piano, such as his Gymnopédies and Gnossiennes. He also wrote music for a Rosicrucian sect to which he was briefly attached.
