My favorite music critic, H. Yoshida, says, I believe, Chopin is a composer of monophony. That could be a reason why I haven't been so much fascinated by his works. Another reason might be that he has composed, mostly, for piano, though I admit his chamber musics are of much value.
Listening to this performance of C sharp minor nocturn originally for piano solo, arranged by Nathan Milstein for violin and piano, I got sure that his works could fit well to string instruments. Monophonic singing instruments.
Midori Goto, the violinist, sings this music from the bottom of the heart. I felt as if I could not breathe while listening to the long lasting phrase sung by her violin. She starts the music from the darkness in pianissimo and goes on the long phrase of melancholy in gradual crescendo to the peak at the refrain of the beginning theme. Then, the tune declines and vanishes into darkness again. It should not be performed brilliantly like a concerto cadenza as often done by the other players. Midori expressed the melancholy in most suppressed manner that appeals us profoundly.
This must be the tune which was sounding in Chopin's mind, I believe, when he was almost dying.
