Pelog (Sundanese: ᮕᮦᮜᮧᮌ᮪, romanized: Pélog /pelog/, Javanese: ꦥꦺꦭꦺꦴꦒ꧀, Balinese: ᬧᬾᬮᭀᬕ᭄, romanized: Pélog /pelok/) is one of the essential tuning systems used in gamelan instruments that has a heptatonicscale.[2][3] The other, older, scale commonly used is called slendro. Pelog has seven notes, but many gamelan ensembles only have keys for five of the pitches. Even in ensembles that have all seven notes, many pieces only use a subset of five notes, sometimes the additional 4th tone is also used in a piece like western accidentals.
^ abc"The representations of slendro and pelog tuning system in Western notation shown above should not be regarded in any sense as absolute. Not only is it difficult to convey non-Western scales with Western notation, but also because, in general, no two gamelan sets will have exactly the same tuning, either in pitch or in interval structure. There are no Javanese standard forms of these two tuning systems." Lindsay, Jennifer (1992). Javanese Gamelan, pp. 39–41. ISBN0-19-588582-1.
