Answer:
A gangsa (not to be confused with the Balinese musical instrument with the same name) is indigenous to the cultures found in the mountain regions (the Cordillera) of the northern Philippines.
Explanation:
A gangsa is a type of metallophone which is used mainly in Balinese and Javanese Gamelan music in Indonesia. In Balinese gong kebyar styles, there are two types of gangsa typically used: the smaller, higher pitched kantilan and the larger pemade. Each instrument consists of several tuned metal bars (either iron or bronze) each placed over an individual resonator.
