Their annual return to the airwaves is not just a tradition but a complex process involving memory mechanisms, social cohesion, and even neuroplasticity. These compositions form a special "soundtrack of the holiday," governed by its own laws of dissemination and perception. Neurobiology and Psychoacoustics of the Holiday Hit The Effect of Priming and Autobiographical Memory. The sound of familiar Christmas melodies (such as the introduction to "Jingle Bells") acts as a powerful acoustic primer.

Traditional songs ("A Little Tree in the Forest," "Last Christmas") have a simple, memorable structure and harmony. Their predictability reduces cognitive load on the brain during perception, creating a sense of comfort, safety, and stability during a period that can be stressful in itself. This is a form of acoustic "cognitive sanctuary). Ritual Function and Synchronization. The joint singing of these songs (at the table, at a morning party) performs a ritual and cooperative function. Synchronization of actions (singing, clapping) through music promotes the release of oxytocin and strengthens a sense of community, which is critically important for family and social holidays.
