When affected in a mourning ritual, the human subject experiments with the necessity of rebuilding his life, taking upon himself the lost that has broken its course. In such a context, rituals proceed to an exploration of the territories of the Other (whatever be his representation) in order to initiate a possible regeneration of life. Then music is not only an accompaniment or a secondary contribution, but a central component of mourning. It makes possible the expression of what is somewhat impossible in the ordinary language : the intimate moves of the being, beneath and beyond the possibilities of the words. It invites the subject to experiment the sublime (sub limen), crossing the frontiers of language, and thus contributing towards his survival.
