Culture of Indonesia and the fusion of Hinduism and animism in Kaharingan; others could be cited. Balinese dances have stories about ancient Buddhist and Hindu kingdoms, while Islamic art forms and architecture are present in Sumatra, especially in the Minangkabau and Aceh regions. Traditional art, music and sport are combined in a martial art form called Pencak Silat. The Western world has influenced Indonesia in science, technology and modern entertainment such as television shows, film and music, as well as political system and issues. India has notably influenced Indonesian songs and movies. A popular type of song is the Indian-rhythmical dangdut, which is
Pencak Silat less direct than other styles, characteristically favouring deception over aggression. Hand movements are used to distract, and openings are deliberately exposed to bluff the opponent into attacking. This approach requires that exponents train their flexibility and stamina. As with Balinese warriors of the past, modern pencak practitioners in Bali often wear headbands as part of their uniform. There are about four main systems considered purely Balinese. The most prominent of these is Bakti Negara, which is firmly rooted in the old local Hindu philosophy of Tri Hita Karana. Another system which has gained prominence is Seruling Dewata meaning "God's flute".
