In opera of Mozart, many different kinds of female characters and personalities presented are quite attractive. Some of the female characters are similar in some way and are good for specific singers to interpret. However, if the singer can analyze and compare the similarity beforehand, the style and personality of the characters can be better interpreted.

The purpose of this research is to analyze two female characters（Susanna from

Le Nozze di Figaro and Zerlina from Don Giovanni）from two operas of Mozart. Two Arias, one from each female character, were chosen to analyze the lyrics, interaction between partner, melodies, and the accompany styles of the symphony.
