Chopin - Nocturne in C Sharp Minor (No. 20)
Chopin's Nocturne No. 20. Although he never published it during his life, it remains to this day one of his most notable works and one of the most hauntingly beautiful piano pieces ever written. The melody captures the sense of hope, but despair at the same time, with Chopin masterfully playing around with tension and resolution and creating a whole world of color just through the piano.
