So  Nagir made a song that made me want to do a piano etude and after many hours of work this song was the result. It sticks to the rules of a piano etude, using only 1 piano, which happens to be complicated like no tomorrow; I'd even warrant that this piece would require three highly skilled pianists to play live. And yes, I used the same picture as  Nagir (with a hue change) and a tempo shift at the end. Done on fl studio using reFX Nexus.
