Fantaisie – Impromptu, Op. 66 by Frederic Francois Chopin
The Fantaisie-Impromptu was written in 1834, but unlike other works that were written during this year, Chopin never published the Fantaisie-Impromptu. Instead, Julian Fontana published it posthumously, along with other waltzes.
This piece has proved to be difficult to pianists for many reasons, one being that each of the hands play in a different meter: the right in duple time, the left in triple time. It also features a middle section in D♭ major, while the beginning and end of the piece are in C♯ minor.
Yet a more complex music box arrangement for the hardest piano song to learn to play on a piano than it originally was this fuckers a doozy lol
