Chopin is my very favorite composer, and I thank you so much for providing this piece. It is my favorite type of music to play on piano: soft, yet overpowering in feeling and emotion;this song is one of my favorites from Chopin, after tristesse and fantasie improptue respectively. My deepest gratitude for giving me the chance to play this.
PARTITION
There's also a very interesting TED piece that uses this tune, well worth checking out:
