Just as someone said that art is an explosion, this work made me think that musical instruments, as a form of emotional expression, create sounds out of joy, anger, sorrow, and the heart. Facing one thing over and over again and honing one's delicacy must be the most painful thing of all, and this work fascinates us with the human condition, in which we sharpen our lives for the sake of expression and sharpen not only ourselves but others as well.
