Music has certainly been linked to humanity since its origins. Throughout the centuries, philosophers, writers, and scientists have sought to understand how music transforms the workings of the mind and influences our emotions and behavior. All religions seem to have maintained complex relations with it, evolving in time and space, between categorical rejection and obligatory integration into practices of worship. Due to its immateriality, music seems to be the artistic form best able to set feelings in motion and to allow an exteriorization of emotions specific to each individual regardless of their beliefs. This elusive aspect gives it a propensity for transcendence. Its emotional power also makes it a very important force for social cohesion. For thirty years, cognitive neuroscience has been interested in music and its effects on brain and cognitive functioning. Behavioral and neuroimaging studies have revealed the brain's significant reactivity to musical stimulation, which shows that humans beings are musical beings in their very essence.
