The most significant of the new contacts was Busoni. The great pianist and composer became Szigeti's mentor during these formative years, and the two would remain close friends until Busoni's death in 1924. By Szigeti's own admission, before meeting Busoni his life was characterized by a certain laziness and indifference brought on by the then-typical life of a young prodigy violinist. He had grown accustomed to playing crowd-pleasing salon miniatures and dazzling virtuosic encores without much thought. He knew little of the works of the great masters; he could play them, but not fully understand them. As Szigeti put it, Busoni—particularly through their careful study of Bach's "Chaconne"—"shook me once and for all out of my adolescent complacency".
