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]
Timpani Timpani (/ˈtɪmpəni/;[2] Italian pronunciation: [ˈtimpani]) or kettledrums (also informally called timps)[2] are musical instruments in the percussion family. A type of drum, they consist of a skin called a head stretched over a large bowl traditionally made of copper. Most modern timpani drums, such as pedal timpani are able to, and are designed to be, tuned easily to specific pitches, often during sections of music; the example being tuned by a movable foot-pedal. They are played by striking the head with a specialized drum stick called a timpani stick or timpani mallet. Timpani evolved from military drums to become a staple of the classical orchestra by the last third of the 18th century. Today, they are used in many types of ensembles, including concert bands, marching bands, orchestras, and even in some rock.
