Why do we make music? Why do certain sounds or music so irresistibly resonate with us? Music is a device which we have, over a vast expanse of time, collectively shaped, with which we communicate and share musical feelings. To study this fascinating piece of technology, we need diverse and cross-disciplinary approaches from acoustic and psychoacoustics, to researches into musical instruments and theories of composition. And in this pursuit, the unity-of-action-and-knowledge （知行合一）becomes crucial. Let’s open our ears, get hands-on and make noise! We are a part of a new sonic culture and we shape future music.
