Salvatore Sclafani was born in Palermo, Italy. His main purpose as a pianist is to find links between music and other arts, especially literature. He holds an MA in Music Performance (Piano) and an MA in Music Pedagogy from the Conservatoire Royal de Bruxelles (Belgium), where he studied with Belgian pianist Eliane Reyes. Among his mentors is also Italian pianistRoberto Plano. He has been awarded several prizes in international competitions, including the International Caraglio Competition and the Premio Crescendo in Italy, the Concours de la Fondation Andrée Charlier in Belgium, and the Concours Festival Répertoire Pianistique Moderne in France. He is currently pursuing a PhD in Arts and Arts Sciences – “Art et Sciences de l’Art” – at the Université Libre de Bruxelles. His research focuses on the influence of Argentinian folk music on selected piano works by Argentinian composers Carlos Guastavino (1912-2000) and Alberto Ginastera (1916-1983). His investigation aims to demonstrate how knowledge of the practices and the formal elements of folk Argentinian songs and dances can directly inform concrete aspects of the interpretation of these works, by bringing together a theoretical-analytical perspective and a focus on technical aspects of piano performance.He is grateful for Nancy Roldán’s kind support of his research efforts on Carlos Guastavino’s piano music and excited to be part of Sonus to contribute to the dissemination of the composer’s art in Europe, especially via lecture-recitals. Salvatore plans on traveling to the Americas in order to begin his field research.Healsocontinues his career as a pedagogue, currently teaching piano performance at Conservatoire de Maubeuge (France), which gives him the opportunity to appreciate Guastavino’s piano works from a pedagogical point of view as well.
