How sound can change everything on screen

 

Sound can really change what's on screen like relationships between two characters for example, with just the change of sound in the background of a scene it can change everything, one sound can make a guy making coffee go from evil to super friendly with just that one change of sound which effects the whole scene. Sound plays a big part in films whether you realise it or not, without the use of different sounds you would not get the experience you should be getting as a viewer. intense music over the top of someone sprinting down a hill could indicate somethings wrong and needs to get to a destination quickly, but if there was upbeat joyful music over the top of it, it would turn into something like he forgot something that he needs for work.
