Different publishers have published different editions of the same piece of music. When a pianist chooses a music score to learn or perform, the details in different music scores will influence the pianist's interpretation. The essay will be divided into three sections. The first section will introduce the piece of music, Vallee D' Obermann and give information about the two editors, Edition Peters and G. Henle. The second will attempt to compare and contrast the differences and similarities in tempo, articulation and dynamic marks in different editions and try to find how the marks influence pianist's interpretation. The final part aims to analyze how the different editions influence the pianist's interpretation in a positive or negative way.
