Gamelan Gamelan (/ˈɡæməlæn/[1]) is the traditional ensemble music of Java and Bali in Indonesia, made up predominantly of percussive instruments. The most common instruments used are metallophones played by mallets and a set of hand-played drums called kendhang which register the beat. Other instruments include xylophones, bamboo flutes, a bowed instrument called a rebab, and even vocalists called sindhen.[2]
Orchestra The typical symphony orchestra consists of four groups of related musical instruments called the woodwinds, brass, percussion, and strings (violin, viola, cello and double bass). Other instruments such as the piano and celesta may sometimes be grouped into a fifth section such as a keyboard section or may stand alone, as may the concert harp and electric and electronic instruments. The orchestra, depending on the size, contains almost all of the standard instruments in each group.
