A Leisurely Play

The Chairlady of this New Year's Eve Party event was the deputy headmistress of the school, named Song Xiaoxia. She was just leaving the hall when Zhao Youyue started to play the piano.

After a few days of rehearsal, Song Xiaoxia was satisfied, especially when it came to the flawless presentation of the two hosts, Zhao Youyue and Huang Zhongzhao. The solos were not perfect, but they were good enough. Only the collective performances such as the choir were giving her a headache, like mice dropping from the ceiling into a saucepan of otherwise perfect broth. 

Song Xiaoxia was a math teacher before being appointed as a deputy headmistress, and she was a math teacher who dearly loved music. She immersed herself into the mesmerizing piano tune played by Zhao Youyue, but a thought came to mind…

Wasn't Zhao Youyue playing the violin? Where did she pull out such an imposing piano performance?
