Legend of the Mountain

I thought Legend of the Mountain was an interesting movie because it drew from a genre so different from martial arts.  I could tell that King Hu was experimenting with different effects and techniques.  Like for example, the yellow smoke, the flashes in the ending scenes, and also the sequences where Ho is in a trance from the drumming.  It's was interesting to see King Hu implement those kinds of techniques into the movie.  There was also a very strong representation of instruments in the movie.  Practically all the ghosts played an instrument.  There was the flutist, Melody played the drums and there were also handheld drums and cymbals included in the film as well.  I wonder if that was a purposeful representation, to include so many instruments into the film.  Meaning that King Hu included instruments to help build on that mystical legend ghost story.  Or if it was for experimental purposes, so that he could experiment with sound manipulation and try new techniques in creating sound throughout the film with the different instruments.
