Bonang

What you see is a traditional Malay musical instrument called a "Bonang". In English, it could be described as "sets of small kettle gongs". This musical instrument originated from Riau (a province of Indonesia), and in the early 19th century, its use spread to the east coast states of Pahang and Terengganu. The bonang is commonly played in Gamelan music together with other instruments such as the saron, kenong, gong and gendang. Malay Gamelan music is usually played during royal and formal occassions, and performers are specially trained in royal palaces.
