To describe Miyazaki's film, composer Joe Hisaishi who is one of Miyazaki's coworkers, is willing to make his films what Miyzaki's think his movies follow nature and recognition of people. One of Hisai's scores is from Miyazaki's film My Neighbor Totoro (1988).
The score above can be interpreted as an ethnic score or animated film's score. But, for me, I have listened to the score many times, and alway felt the score makes me calm and bring me back to when I was around at age of five.
As I said, soundtrack could be filled more than half of making film process to make memorable for the audience so that the audience might enjoy watching by choosing preferred films. Eventually films are made in the world. If you had time to watch foreign films, such as I introduced on this post, you may get the sense of what movie fans are like in the country and could gain an an idea of the culture.
