Be one with sounds, feel it as entities that influence your body until your soul, from those complex and musicals to the simplest ones, all of them have relevance in their goal of transport a human being to a particular experience.
Daily we express emotions produced by elements from our world, one of them is the sound, you go out from your house and enter to that noisy city full of cars, people screaming, machinery, etc. and you feel that desperation, sometimes anger, you want to escape quickly from this huge and annoying site until you arrive to your workplace, depending how it is, your sensations can emerge, there could be a fatal silence accompanied by printers, photocopiers, and other elements of the everyday, you start to feel boring but suddenly, you hit a pen against a pencil holder, then your hands over the table and after a while you are getting fun with your musical percussion that you built, until your neighbor ask for silence.
However, no all the experiences can be negative, a really nice place is the nature where our feeling of appreciation of life arises; joy, happiness, and peace you can feel when you hear those birds in harmony with the rustle of vegetation produced by a whistling wind, or from our home and with people we love, we can enjoy pleasant whispers that relax us after a tiring day along with caresses and good wishes.
Sounds also influence us physically, depending on the emotions that they produce we vibrate intensely, either positively or negatively, so if we think in some sounds for creating an experience we have to take into account that they could influence in an emotional and physical way, something interesting about it is the Autonomous Sensory Meridian Response (ASMR), which is not totally valid scientifically, but it could contribute to our knowledge about what the sounds could make in us.
In To Leave each experience that we want to transmit is reinforced with sounds that are thinking for particular emotions, that is why we want the player to be projecting deeply in the game, reflect about his life with that sensations that plow his body and soul, and thus transcend and learn from himself.
