In Blue Velvet, Lynch uses sound and music in several different ways, to enhance atmosphere, establish mood, but also sometimes to help telling the story itself.
Indeed, first, BadalamentiÃÂÃÂs score contributes to complete the filmÃÂÃÂs themes. Lynch depicts a seemingly beautiful and quiet small town, but like everything, a hidden side reveals evil, pain, madness. The music denotes this hidden side, and even mystery and darkness.

All the ÃÂÃÂsupposed diegeticÃÂÃÂ sounds are first off (fire truck, children ÃÂÃÂ actually quiet, TVÃÂÃÂ ), and the first that we hear is the...
