Fantaisie Impromptu, Op. 66

Frédéric Chopin composed Fantaisie Impromptu, Op. 66 as a private solo piece that eventually became a staple for technical players. Most people recognize the middle section from the 1917 song I'm Always Chasing Rainbows or various classic cartoons where a character plays a piano at breakneck speeds. It shows up constantly in rhythm games and classical music memes because of its polyrhythmic structure. Playing this on a Roblox piano requires a lot of finger independence. The right hand handles fast sixteenth-note runs while the left hand stays in a steady triplet rhythm. It is a four-against-three pattern. The speed makes it difficult to master on a computer keyboard without ghosting issues. This Roblox piano sheet captures that chaotic energy perfectly. The transition from the fast outer sections to the slower, melodic bridge feels rewarding after hitting all those notes. It is pure chaos for your hands.
