Waltz No. 15 in E major, Op. posth. by Frédéric Chopin


'''Waltz in E major''' is one of his lesser known waltzes, discovered in his folder containing musical works that he did not want to be published.

It was written in c. 1830 and published in 1871/72. It was the second of Chopin's posthumously published waltzes not to be given a posthumous opus number. (The first was the Waltz in E minor.) It appears in Brown's catalogue as B. 44, in Kobyla\u0144ska's catalogue as KK IVa/12, and in {{ill|pl|Józef Micha\u0142 Chomi\u0144ski's as P1/12.
