Ofelia's mother told her that mermaids can heal all sorts of diseases. But it is not a natural skill, it should be honed. And someone as young as her could not even close a scratch yet.
"You must focus on invoking the power of sound, Ofelia. You shouldn't try to control it, but instead, let it control you." Her mother suggested. "Once it calls out to you, knowing that you needed it, that it is when you must answer its call back."
"Ofelia doesn't understand, Mother..." The little siren scratched her head. "It's so difficult."
"Soon, love. Soon, you will. Sound travels through the wind, and like the wind, it is restless. It has no master, and yet, currents exist. Therefore, what you must do is let your voice swim along with these currents, and let them take you to where you want to be. Like the sea, all things will be brought to their rightful place. Because we are creatures of the sea. And so, we may never get lost in it."
