Yanco (1961)

The engaging and sentimental tale begins when the little boy (Ricardo Ancona) starts manifesting a greater and greater talent at music and at the same time, a supersensitivity to sounds. His overly astute hearing drives him into the woods and away from the cacophony of the town's hustle and bustle. Once in the woods, he meets a kindly old hermit who teaches him how to play the violin he made. After the old man dies, the violin ends up at a pawn shop, and each night the boy sneaks in to play it in secret. It is this haunting, nightly music that sets the town on edge -- people think an evil spirit is on the loose.
