Soon he was giving concerts in various surrounding cities, including Liège and Brussels where he met the violinist Charles Auguste de Bériot, with whom he began studies.
He had aspirations of becoming a composer as well and, having already taken lessons with the respected Simon Sechter in Vienna, spent the winter of 1835–1836 studying composition with Anton Reicha in Paris. His first violin concerto, later published as Concerto No. 2, dates from this time.
His Violin Concerto No. 1 was acclaimed when he played it in Saint Petersburg on his second visit in 1840 and in Paris the next year; Berlioz found it "a magnificent symphony for violin and orchestra".
