Sound of my Thriller

Background sound is not really an issue for my production. The only sound I'm going to put is of the antagonist walking, the sound of taking steps which creates tension for the audience because the identity is hidden and it is going to be a POV shot. make the audience feel like a the character for a bit. The other sound I'm going to put is the Little nursery/ baby songs. This is because it creates sympathy for the protagonist and make you wonder about his daughter. the theme song is going to be the baby music as well.
