Walking through Grand Central Station is like experiencing a symphony. The sound created is an unintentional collaboration appealing to many senses. The colossal ceiling echoes the percussive footsteps and timbres of the voices, making the music come alive. The breezes carry a variety of scents, adding flavor to the dimension of sound. At Grand Central, people, unbeknownst to them, contribute to the entire production, and as an observer, I am mesmerized. It fascinates me that players in a symphony work together, united under a different ceiling to perform, while the ensemble in Grand Central inadvertently produces music that changes every single second.
