'A truth whispered among animatiors is that 70% of a show's impact comes from the soundtrack' 

Michel Dougherty

I agree, without dramatic music in tense times during a film, the emotion wouldn't be experienced as much as just watching a film with no music. Soundtracks help set a scene. Creates mood and atmosphere.

Different types of sound:

Music

Voices

Sound effects

Senses:

Hear

Watch

Feel (Emotionally)
