Solresol (Solfège: Sol-Re-Sol), originally called Langue universelle and then Langue musicale universelle, is a constructed language devised by François Sudre, beginning in 1817. His major book on it, Langue Musicale Universelle, was published after his death in 1866,^[1] though he had already been publicizing it for some years. Solresol enjoyed a brief spell of popularity, reaching its pinnacle with Boleslas Gajewski's 1902 publication of Grammaire du Solresol.

Today, there exist small communities of Solresol enthusiasts scattered across the world.^[2]
