Music Life
"Music is the art of thinking with sounds." -- Jules Combarieu
Western classical music always fascinates me. I love listening to and studying the masterpieces
of almost all genres. Besides the heart-touching experiences, it is always fun and rewarding to
make even a tiny discovery in a beautiful work. Towards deeper understanding, I still need to
grab more systematic knowledge on harmonics, music form and other important music theories.
I have been learning to play the violin for more than 10 years. It is such a great instrument that I plan
to spend my whole life to master the virtuosity. I had also been a member of Tsinghua University
Symphony Orchestra (TUSO) from 2004 to 2007. During the period, we rehearsed more than 20 masterworks
and gave many concerts inside and outside the university.
