Pelog

Pelog is a tuning system used in Indonesian gamelan music. It provides an octave-repeating heptatonic scale, although octaves are usually stretched to account for the high inharmonicity inherent to gamelans and (in Bali) to produce complex beating patterns known as ombak.

In Javanese gamelan, the tones of Pelog are numbered 1 through 7 (traditionally associated with body parts: 1 = head, 2 = neck, 3 = chest, 4 = groin, 5 = knees, 6 = feet, 7 = hands). The exact tuning varies considerably between gamelan, but on most modern Javanese sets one would encounter in North America the pairs 1-5, 2-6, and 3-7 are roughly fifths.

Traditionally, there are three pathet, or modes, of Pelog. Pelog nem (or pathet nem) uses the tones 1 – 2 – 3 – 5 – 6 with an emphasis on either 6–2 or 5–1 depending on the piece (technically, depending whether the piece is emulating Slendro manyuro or Slendro songo). Pelog barang uses 2 – 3 – 5 – 6 – 7, usually emphasizing 6+2 or 3+7. Pelog lima is a sort of "odds and ends" for uses of the 1 – 2 – 3 – 5 – 6 scale that don't really fit into anywhere else. Definitions are somewhat fuzzy and may vary by gamelan master. The 4 tone is not often encountered, and some elaborating instruments lack the tone entirely.

Pelog is well-approximated by the seven note "antidiatonic" (2L 5s) scale of 9edo. This is essentially an inverted version of the 12edo's diatonic scale, where the steps are Half–Half–Whole–Half–Half–Half–Whole instead of Whole–Whole–Half–Whole–Whole–Whole–Half. However, in practice Pelog's exact intervals are slightly different throughout the scale, while 9edo supposes exactly two distinct interval sizes.
