the Abbaye Saint-Pierre de Solesmes. Nevertheless, it benefits from the careful study of neumes by Dom and his pupils ("Gregorian semiotics", musical palaeography). It is a comparativism tributary to ethnomusicology, insofar as it relates to each other the writings of the Middle Ages (noted manuscripts, treaties) and the traditions currently alive. This approach is also illustrated by the work of Hungarian musicologist Benjámin Rajeczky, as well as by the interpretations of Marcel Pérès. According to the same spirit, the series Diaphonia, created by Jacques Viret in 2000 with the "À Cœur Joie" publishing house in Lyon, provides amateur choristers with a repertoire of medieval songs transcribed in modern musical notation so as to restore all the finenesses of the original notations and add data which are not included therein and come from other sources. An integral science of music The work of Jacques Viret is based on a rigorous investigation from sources, as required by scientific musicology. However, they broaden the historicist positivism and music analysis, where it is generally confined to two correlated movements: On the one hand, the musical philology of Jacques Chailley, which elucidates the general laws of musical languages and their perception; On the other hand, the , which reconciles modernity and tradition, science and spirituality. Jacques Viret is today one of the very rare musicologists claiming the New Paradigm; In this capacity, he joined the team by . His perspective, therefore, is defined as totalizing and holistic: the musical fact is considered not only from the objective and partial angle of ordinary musicology, but from that of the receptive or active subject (his consciousness), beyond the cleavage between the various types of music. Explanation and commentary then restore its legitimate primacy to sound in the face of writing, and closely link the musical meaning to the human being in its threefold constitution of body, soul, spirit. They restore, in a new form, the "musical science" of Pythagorean obedience cultivated in Ancient times and in the Middle Ages: highly rational on one side, in its mathematical slope; Irrationality of the other, in its sensitive, intuitive, even magical (ethos theory, derived from the primitive incantation). In the eyes of the thinkers of German Romantism also - among others Schopenhauer, admired by Richard Wagner –, music is much better than an art of pleasure: language of the soul, interiority, revelation of the unspeakable, it opens an access to
