The balungan (Javanese: skeleton, frame) is sometimes called the "core melody" or, "skeletal melodic outline," of a Javanese gamelan composition. This corresponds to the view that gamelan music is heterophonic: the balungan is then the melody which is being elaborated. "The part most frequently notated by Javanese musicians, and the only one likely to be used in performance, is the instrumental melody called balungan (literally, 'skeleton', 'outline')."
The group of instruments which play the closest to the balungan are sometimes also called the balungan, or balungan instruments. These are the saron family and the slenthem. In many pieces, they play the balungan. However, they can also elaborate on the parts in a variety of techniques. It is possible that there is no instrument playing the balungan, although many musicians claim that the balungan is still present.
The term has been a source of some controversy, as various writers may define it differently. Sometimes it is identified with the melody played on the saron (whose range is limited to an octave), but sometimes it is identified with a wider tessitura that is implied by the patterns on other instruments. This multi-octave melody is the one given in kepatihan notation, the cipher notation used for gamelan pieces.
Lagu is a related term, which is used by Sumarsam and is sometimes translated as "inner melody." It can mean the multi-octave balungan, or a more implicit melody. There is no consensus on the use of either term, and they may be used differently by different writers or in different contexts.
- "The center of gravity of a gamelan composition, and the improviser's guideline, is a melody known as the 'skeleton' or 'framework' (balungan), played in a slow, even rhythm on [the]...saron."
- "An abstraction of the inner melody felt by musicians."
- "If the balungan is the same, then the elaborating parts should be the same."
