For a performer, regardless of who the composer is, in order to interpret a piece to its fullest expression, one must spend time to gain insights to the composer's personality, preferences and the content of the composition, and try one's best to achieve intimacy with the composer's feelings. This thesis explores Chopin's creative background, teaching method, musical form and expressions, through Ballade No.1 in g minor, Opus 23. In this exposition, we come to learn that the creative background to this piece was heavily influenced by the Polish poet, A.B. Mickiewici (1798~1855), expressing his patriotic spirit and, hence, the music leans toward classical sonata form. As one reaches an understanding and appreciation of the music's character, it enables the performer to express this well-known music piece to its fullest.
