Cette catégorie propose des créations sonores conçues comme un accompagnement complémentaire à votre démarche personnelle de bien-être et, le cas échéant, à un suivi médical déjà établi avec votre médecin traitant ou votre spécialiste. Les musiques proposées ont été créées dans une intention d’apaisement, de relaxation profonde et d’harmonisation. Elles intègrent différentes fréquences inspirées notamment des travaux et recherches attribués à Royal Raymond Rife (1888–1971) et à la docteure Hulda Clark (1928–2009). Chaque personne pouvant vivre et ressentir l’écoute de manière différente, ces créations sont avant tout proposées comme une expérience sonore invitant à la détente, à l’écoute de soi et à un moment de pause. Ces musiques ne constituent pas un traitement médical et ne remplacent en aucun cas les recommandations ou traitements prescrits par un professionnel de santé, ni une alimentation équilibrée ou la pratique régulière d’une activité physique.

What is 432 Hz music?
Verdi champions the “scientific pitch” of 432 Hz.
432 Hz music is tuned with an A at 432 Hz instead of the international 440 Hz standard. Listeners often describe this pitch as warmer and rounder, conducive to letting go.
In 1881, Giuseppe Verdi campaigned for this pitch, worried about singers' vocal fatigue. Italy adopted it in 1884 for its military bands, before 440 Hz prevailed in the 20th century.
What does research say? Pilot studies on small samples report a lower heart rate and better sleep. The results remain preliminary, and we say so plainly.
Instrumentation follows intention
The cello is at the heart of every piece. Depending on the intention, Mathyas surrounds it with piano, guitar, percussion or voice: nothing is generated, everything is played.
Depth
Cello
The low register carries the emotional accompaniment, closest to the human voice.
Clarity
Piano
Clean lines and a stable frame, for listening when the mind needs to settle.
Softness
Guitar
A warm, close texture, for falling asleep and the end of the day.
Drive
Percussion
A rhythmic support for pieces that accompany getting going again.
Presence
Voice
Most often without words: the voice as a timbre, so you are not left alone.
Mathyas Voisin, cellist and composer
“Not the applause: a breath that slows down, a tension that lets go, an evening that becomes bearable again.”
A cellist since the age of four, with a background in psychology, he has accompanied Grand Corps Malade, Slimane, Gims and Amel Bent on stage. Certified in sophrology since 2024, he now writes pieces built on the rhythm of a breath. He promises no cure and replaces no one. Every note is played, none is generated.
