Sometimes, a piano and an open soul is all you need to express all the emotions a human can feel. Nocturne Op. 9 No.2 by Frédéric Chopin is a lovely piece that really does bring that essence to reality.
It may sound like an easy piece to play, but this Nocturne requires a balance in technique, but also in the spirit within yourself. You really do have to feel at peace, or something like that, to truly bring out the beautiful music that resides within this piece.
I think writing more about this Nocturne will be a waste of space. This piece will speak for itself. No- it will sing for itself.
