Guillaume started to play accordion aged six under the guidance of Patrice Soulié in his hometown of Aurillac (France). He won his first prize the following year at the UNAF’s competition in Paris. His passion for music took him to the CNIMA where he studied with Jacques Mornet and took part in many Masterclasses (with Roman Jbanov, Yuri Shishkin, Franck Angelis among others). During this time he acquired many others prizes to add to his palmares, including the SACEM’s Prize and a 2nd Prize at the international competition of Montrond-Les-Bains. Guillaume has been studying at the Conservatorium Van Amsterdam with Marieke Grotenhuis and Marko Kassl since September 2015 where he developed a great admiration and devotion to Bach’s music, and was recently accepted at the Royal Academy of Music in London, to prepare his Master diploma with Professor Owen Murray. Guillaume aims to reach the highest technical level for serving what is the essential in this art : Musicality, Sensivity and Authenticity! As a classical accordionist, to participate to the development of this unique and versatile instrument in the Classical Music world (which yet, doesn’t get enough credit compare to its possibilities) is a duty he feels responsible to achieve. The growing stature of the classical accordion has provided Guillaume the opportunity to introduce all the possibilities and compatibilities of his instrument to the classical music’s world.
