 In the southwestern part of Central Java, which is usually named the Banyumasan region, a cultural mingling occurred; bringing together Javanese culture and Sundanese culture to create the Banyumasan culture.In the central Javanese court cities of Yogyakarta and Surakarta, contemporary kings trace their lineages back to the pre-colonial Islamic kingdoms that ruled the region, making those places especially strong repositories of classical Javanese culture.Classic arts of Java include gamelan music and wayang puppet shows.
