It is...?

Imagine a phenomenon so pervasive that it permeates every corner of human existence. Its invisible influence possesses the power to evoke the deepest of emotions, from exuberant joy to the depths of sorrow. This entity is so powerful that it can even significantly influence physical behavior, altering decisions and actions so strongly that the human would feel possessed by an unseen and indescribable force. 

Found in cultures across the globe, this phenomenon has existed since the dawn of human civilization, iterating upon itself through the ages. It’s present in our most intimate moments and our grandest celebrations; its various forms can be simplistic or complex, spontaneous or carefully orchestrated, linear or multifaceted. Regardless, its impact remains profound.

In the realm of science, this phenomenon has been subject to intense study, with researchers discovering its capabilities of affecting brain activity, of healing and harming, of synchronization and cooperation, or conversely, of mass hysteria. Its mere presence can increase productivity, enhance learning experiences, or induce relaxation. However, in certain forms, or if it overstays its welcome, it has been known to cause discomfort, disrupt cognition, or contribute to various forms of unrest and agitation.

This phenomenon also holds significant commercial value: industries have been built around its creation, dissemination, and consumption. It is heavily used in marketing to influence consumer behavior, in movies to accentuate climaxes, and in political arenas to rally and unite, with its creators revered, gaining immense influence. 

Despite its omnipresence and undeniable power, individuals often take this phenomenon for granted, rarely stopping to consider its true impacts on their everyday lives, or on society at large. Thus, it lives on, as a backing track to each individual, shaping experiences, memories, and identities. 

Yet, this extraordinary force is nothing other than music, with its power to unite and divide, to heal and harm, to build up and tear down. It is an art form so engrained in human culture that its powers are often invisible, yet its presence is as vital as the air we breathe.
