Below is a link to a great, very comprehensive overview of the tinikling, a native Filipino dance. The dance is always accompanied by a song that could very well be considered as a folk song because of its traditional nature. This song is a good example of unblemished, un-Westernized Filipino music, as it has been around for a very long time and was developed by people in the provinces.
