Early on, Diego Tosi benefited from a musical education initially centred on the piano, before receiving his first violin lessons at the age of 5 with the violonist Philippe Couvert. A year later, at the National Music School in Aulnay-sous-Bois, he was taught by Jean Lenert, while continuing his piano studies with Dominique Mercier.
At the age of 13, he enrolled at the Paris Conservatoire (CNR) to further his training, continuing to study violin with Jean Lenert. At the end of his academic cycle there, he obtained a First Prize with highest honours, followed by an advanced prize.
Noticed by Jean-Claude Casadesus, he played the solo violin part under his direction in a performance of Rimski-Korsakov’s Scheherazade at the Théatre des Champs-Elysées with the Symphony Orchestra of the Paris Conservatoire. In 1998, at the Paris Conservatoire (CNSM), he entered the class of Jean-Jacques Kantorow from whom he took tuition for three years. At the end of that cycle of studies, he was awarded his Prize of Paris with highest honours voted unanimously by the jury.
He also attended the master class of Alexandre Benderski before going to the United States for advanced study. Thanks to the Lavoisier Fellowship, which he won hands down, he was given the opportunity of attending the University of Indiana in Bloomington to study with Miriam Fried.
Earlier on, he competed in competitions for young artists under 20 and successively won Second Prize at the Germans Claret International Competition in Barcelona, Third Prize at the Inter-national Young Soloists Competition in Wattrelos, First Prize at the Canet International Competition (these both in France) and, most recently, First Prize at the Moscow International Competition.
Diego Tosi holds today a position of solo violinist within Pierre Boulez’s Ensemble Intercontemporain.
