Every three years the Canada Council holds a competition for string players to use rare instruments for three years. “For the second time, Yi-Jia Susanne Hou, a 28-year-old violinist raised in Mississauga, Ont., has won first prize in the violin competition. That gave her first pick of instruments, and for the second time she has chosen a 1729 ex-Heath Guarneri del Gesu violin.”
