Frédéric Chopin is one of the most important composers of Romantic period whose piano pieces are well loved by the world and are popular repertoires of concert performers. However, 24 Preludes Op. 28, seems to be underestimated of its importance if compared to Chopin’s other works. Thus, the purpose of this study is to offer a better understanding of 24 Preludes through detail discussing of style characteristics and musical interpretation from the standpoint of performer and pedagogue. After a short introduction of preludes’ background, the author investigates the musical style characteristics, including formative influences, melody, harmony, form, structure, mood and pedal; then, a brief analysis and interpretation of each prelude; finally, categorizing 24 Preludes into 4 levels according to their difficulties of technique. It is hoped that this paper may serve as a reference for performers and pedagogues and bring up their interest to this wonderful composition.
