Music functions as a fundamental medium of expression that shapes human behavior and culture by directly influencing emotion, perception, and internal states. Through rhythm, tone, and harmony, it organizes feeling and experience, often bypassing purely cognitive processing to create immediate, embodied responses. Music guides mood, attention, and social connection, reinforcing memory and shared identity across individuals and groups. As it is created and experienced collectively, it becomes a carrier of cultural meaning - transmitting values, stories, and patterns of resonance that shape how people relate to themselves, each other, and the world around them.
