Giorgos Thymis was undoubtedly the great musical personality of the city of Thessaloniki in the second half of the 20th century. He was a source of inspiration for the younger generations, whom he loved selflessly, he stood by their side whether they were his students or not and he left behind the initially Panhellenic and then International Competition that bears his name.
