Violin maker Jan Nemcek knocks on the future violin body to hear the sound, in the northern Serbian village of Kovacica, Wednesday, Oct. 4, 2017. Nemcek picks up his own wood from the forest, cuts and dries it himself and then slowly and patiently moulds it into a musical instrument. Nemcek is a violin maker a rare one that makes violins the old way _ using no machines, but only his hands and tools. (AP Photo/Darko Vojinovic)
