The research and reflection of Jacques Viret refer essentially to the notion of tradition as defined by René Guénon in the line of the perennialism : Not as the preservation of a fixed legacy, more or less ancient, but as the manifestation, diversified according to cultures, epochs and disciplines, of a "sacred, universal and timeless truth", a fruitful source of inspiration and creativity, in perpetual becoming and renewal. For music, Pythagoras remains, in this respect, a permanent reference. The series of harmonics thus appears, as an audible expression of numbers and proportions, as an image of the cosmic order. The universal creative principle is symbolized by the fundamental frequency in the har:monic order, by the tonic of the modes in the melodic order. In particular, the tonic sol, "sun" in Latin, the central element of the theological and esotericcryptogram that Jacques Viret discovered in 1978 in the notes of the range and of which Jacques Chailley completed the explanation. The official liturgical chant of the Roman Catholic Church, the Gregorian chant is especially the expression par excellence of tradition for the music of the West. Jacques Viret studies it in this light. He highlights, upstream, the rooting of this corpus in the other musical traditions of the world, especially oriental before the year 1000, which is very different from the style instituted in the Nineteenth by the Benedictines of the Abbaye Saint-Pierre de Solesmes. Nevertheless, it benefits from the careful study of neumes by Dom and his pupils. It is a comparativism tributary to ethnomusicology, insofar as it relates to each other the writings of the Middle Ages 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.
The work of Jacques Viret is based on a rigorous investigation from sources, as required by scientific musicology. However, they broaden the historicistpositivism 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, 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. 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 the "Soul of the world". The anthropological humanist musicology, which is promoted by Jacques Viret, integrates the contributions of Carl Gustav Jung's psychology, Gestalt psychology, analytical psychology, transpersonal psychology, neuropsychology). It ramifies towards aesthetics, acoustics, hermeneutics, symbolism, metaphysics, sociology, music therapy, pedagogy, psycho - pedagogy, and rhetoric, and includes research on the interpretation allowing to execute the old repertoires according to their authenticity. It revalues the orality as a living vehicle of traditional practices and knowledge, bearing precious values: vital, human, spiritual. This broad, open, spiritualist conception of musical science confers their originality to the works that Jacques Viret has published since 2004 at, about gregorian chant, Medieval music, Richard Wagner, musicothérapy, Baroque music, and opera. Among the transverse problems that they expose, one will particularly mention that of singing in relation with the speech, as the most direct expression of the feeling or musical instinct, and this, from the early childhood.
