Two Sonatas of Frederic Chopin

I listened to Chopin's two Sonatas today. He wrote three sonatas for piano in his life.
The first sonata was written when he was a student in Warsaw. I don't think it's so bad though, but quite few pianists play that sonata quite infrequently. The other two sonatas are really famous pieces. If you would like to be a pianist, you would have learned and played these sonatas. Those require your quite high level of piano techniques for playing the sonatas. I used to struggle with the difficult part in those. I especially like the third movement in the third sonata.

Do you ever know this Japanese word Hakanai? I haven't yet found the perfect English translation for that, though. The word means sweet separation feelings for your beloved thing (or person who has just passed away) which has extremely short life. I feel fleeting tranquil and sweet moments whenever I listen to the third movement. It sounds as if I were in fresh open air in autumn for me.
