Chopin Largo in E-flat major, B. 109

Frédéric Chopin wrote his Largo in E flat major in 1837, though the work was never published during his lifetime. As it doesn't have an opus number, it is usually referred to by its Brown catalogue number, B. 109a. Like many of his lesser works, it was published posthumously (in 1938), contrary to his wish that all his unpublished manuscripts be burned.
