Guillaume Beaulieu started learning recoder at the age of ten, in the music school of Massy, teached by Maud Caille. After the obtention of his recorder prize in Jean-Pierre Nicolas's class at the CRC of “la Valée de Chevreuse” in 2009, and of his complete DEM in 2010 with the chamber music prize, he integrated Pierre Hamon's class at the CNSMD of Lyon in 2011. His taste of ancient music helped him to experience other instruments, especially polyphonial ones ; he learned harpsichord at the CRD of Orsay, as well as theorb at CNR of Versailles.
This versality gave him the opportunity to play both recorder and theorb with several formations, and he often take part in live performance with the masterie of the “Centre de Musique baroque de Versailles”, under the direction of Olivier Schneebeli, or Partock Cohen-Akenine at the Versailles castle. He was selectionned to take part in 2010's and 2012's session of “l'Orchestre Français des Jeunes Baroques”, in which he played under the direction of Paul Agnew at the “Opéra Comiqe” in Paris, and at the “Grand théâtre” at Aix en Provence.
