Angklung is a world heritage instrument that is an important part of Indonesian culture. House of Angklung Surabaya (HoAS) is a social venture in Surabaya, East Java, Indonesia that teaches angklung lessons to children in impoverished parts of Surabaya, Indonesia so they can gain the discipline of learning a musical instrument. Students learn to play, and then learn to teach the angklung, while also being paid for their performances. Performing inside a university allows them to interact with teachers and other university students who inspire these at-risk youth and their parents to consider attending university.
