The purpose of writing this article is to describe the results of research on changes in the function of angklung in Tasikmalaya, West Java, before and after Indonesian independence. The research method uses ethnography. Data were collected through interviews with angklung figures, observations of angklung games, and documentation studies. The results of the study illustrate that the Angklung art in the Balandongan area before Indonesian independence functioned as an information tool to give a signal to the public of a danger, then functioned as a game of angklung adu or Tarung kojor, to find champions (martial arts experts) in order to fight the Dutch colonialists. After independence, the function of the angklung sered changed its function as a performing art. The art of angklung fighting (fight to the death) changed its name to angklung sered. The name sered itself is taken from the form of the show, namely pushing each other (silih sered) to eliminate previous negative judgments about the existence of angklung fighting which contains elements of violence.
