🔗 Solresol

Solresol (Solfège: Sol-Re-Sol) is a constructed language devised by François Sudre, beginning in 1827. His major book on it, Langue Musicale Universelle, was published after his death in 1866, 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. An ISO 639-3 language code had been requested on 28 July 2017, but was rejected on 1 February 2018.

Today, there exist small communities of Solresol enthusiasts scattered across the world, able to communicate with one another thanks to the Internet.
