The children’s souls should have youthful voices but with an undercurrent of deep melancholy and loss. The tone must be clear and emotionally charged, with a sense of both innocence and tragedy. Their voices should have a slightly ethereal quality, almost as if they are speaking from another realm, with a delivery that balances fear with courage. References might include the vulnerable tone of Coraline (Dakota Fanning) or other child characters who navigate between the real and supernatural worlds.
