Music have an amazing impact on us, it can make us sad or laugh. It can move us in an impossible ways without even words. Music has become a part of us without us realising, it is that powerful, impacting and sets our emotions free.
“The right music can help your animation flow, and sound effects can give your work a solid feeling that adds to the illusion of life.” Mark Simon.
The sounds that are in animation or film are:
Ambient or natural sounds
Sound effects
Sound tracks
Narration
Dialogue
Without all of these sounds an animation would be lifeless. All of the sounds in an animation plays a major role in creating a perfect animation. Sound effects can show the interpreter what the character is feeling and thus the interpreter will take that into account. Narration can help the interpreter in a massive way for it helps the watcher to understand what is happening when there is no movement.
Dialogue helps to build depth to a character and can also emphasise the type relationship between two or more characters.
With the right music it makes the animation amazing or horrendous, it is up to the creator to pick the right music so that interpreter can feel what the creator is trying to say through the characters behaviour and attitude.
“A truth whispered among animators is that 70% of a show's impact comes from the sound track.” Michel Dougherty.
I totally agree with Michel Doughtery said, without the sound tracks an animation does not build up emotions, it doesn't put us into the characters shoes and help us to experience what they're feeling. Even if a character in an animation is smiling it doesn't convey their feeling towards us, e.g. character A kills character B, a smile appear on character A's face. If there was no sound track in the background, the interpreter would not know how to convey this information. So if the animator put's a triumphant sound track in the back ground, the watcher will interpret it as victory or if the animator puts a sinister sound track in the background of the killing, the interpreter will convey the information of the killing as evil.
Therefore sounds play a major part in animation it helps us to take in the information easier without us feeling astray from the animation. It helps us to interpret it better and can put ourselves in the characters shoes.
