This particular piece, No. 4, is written in two different keys, G major and E minor. It consists of 26 measures, and has the potential to evoke a wide range of emotions. It is a work of remarkable delicacy, with gentle and fragile melodies that crescendo and subside, and create a beautiful, meditative atmosphere. The mix of major and minor keys gives the piece an intriguing depth and tension, while its relative brevity makes it a perfect example of Chopin's musical genius.
