Introduced into the world of music from an early age thanks to his sister, Stéphanie Varnerin, debuts in the study of guitar at a very young age. It is not, however, until he receives his Baccalauréat in Science, when he decided to devote himself entirely to the study of music.

He received his first awards in the Nice conservatory in the guitar class of Tristan Manoukina, where he was awarded the first guitar and chamber music award. Later, upon reception of his Diploma on Musical Studies, he left for Paris to join the guitar class of Judicaël Perroy to perfect his technique. During that time, he met several grand masters of guitar in several courses, magisterial classes and international competitions, such as Roland Dyens, Alberto Pons, Raphaëlla Smith or Fabio Zanon. It was finally in Switzerland, within the guitar class of Dusan Bogdanovic, where he concluded his academic instruction through the reception of a Master’s Degree in specialized interpretation and a second Master’s Degree in Pedagogy. At the same time, he received a certificate for advanced studies in Kodály pedagogy from the Kodály institute of the Franz Liszt Music Academy in Budapest.

To date, his work is divided in solo concerts, orchestra projects for the delivery of concerts, invitations to participate in operas, among which stand the part of soloist guitar chair during the creation of the J.M Curti opera in Geneva, the chamber music for concerts of the Varnerin Duo, as well as teaching the guitar class at the Lausanne Superior Music School and in the Kodály Music School in Geneva.

Of a curious nature, Mathieu enjoys discovering new horizons, which he integrates into his music. For this reason, he has partaken in magisterial classes of ethnomusicology by Simha Arom, of the Jazz improviser Bruce Arnold (professor at New York University), of Indian music at the Haute Ecole de Musique of Geneva and he also plays the lute.
