'''Pelog''' refers to 7-note [[tuning]]s used in Indonesian gamelan music. There is no one definitive pelog scale, as there is considerable variation between gamelan, and especially between different regions (in particular Java, Bali, and Sunda).

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~~.

== Javanese gamelan ==

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 it is not uncommon for the pairs 1-5, 2-6, and 3-7 to be approximated by [[3/2]].

Traditionally, there are three ''pathet'', or modes, of Pelog. ''Pelog nem'' (or ''pathet nem'') uses the tones {{dash|1, 2, 3, 5, 6|d=med}} 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 {{dash|2, 3, 5, 6, 7|d=med}}, usually emphasizing 6+2 or 3+7. ''Pelog lima'' is a sort of "odds and ends" for uses of the {{dash|1, 2, 3, 5, 6|d=med}} 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 [[5L 2s|diatonic scale]], where the steps are {{dash|Half, Half, Whole, Half, Half, Half, Whole|s=|d=med}} instead of {{dash|Whole, Whole, Half, Whole, Whole, Whole, Half|s=|d=med}}. However, in practice Pelog's exact intervals are slightly different throughout the scale, while 9edo supposes exactly two distinct interval sizes.
