In 1727, Stefan Silbermann is a grief-stricken thirteen-year-old, struggling with the death of his mother and his removal to a school in distant Leipzig. Despite his father's insistence that he try not to think of his mother too much, Stefan is haunted by her absence, and, to make matters worse, he's bullied by his new classmates. But when the school's cantor, Johann Sebastian Bach, takes notice of his new pupil's beautiful singing voice and draws him from the choir to be a soloist, Stefan's life is permanently changed.
