Chopin Waltz in E-flat major, B. 46

Fréderic Chopin completed his Waltz for solo Piano in E flat major, between the years 1829 and 1830. It was published posthumously in 1902, bearing a dedicatory to Emily Elsner. Since then, there have been claims of the waltz being a spurious piece. It received no Op. number upon its publication: instead it was catalogued as B. 46 (according to Brown's catalogue of Chopin's work).
