'''Pelog''' is a [[tuning system]] used in Indonesian gamelan music. It provides an octave-repeating heptatonic [[scale]], although [[stretched and compressed tuning|octaves are usually stretched]] to account for the high inharmonicity inherent to gamelans and (in Bali) to produce complex beating patterns known as ''ombak''.<ref>Sethares, W. A., & Vitale, W. (2020). ''Ombak'' and octave stretching in Balinese gamelan. Journal of Mathematics and Music, 16(1), 1–17. https://doi.org/10.1080/17459737.2020.1812128</ref>

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.

Line 7:

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]]. However, in practice Pelog's exact intervals are unequal throughout the scale, while 9edo supposes exactly two interval sizes.

Pelog is well-approximated by the seven note "antidiatonic" ([[2L 5s]]) scale of [[9edo]], which is essentially an inverted version of the [[5L 2s|diatonic scale]] of 12edo. However, in practice Pelog's exact intervals are unequal throughout the scale, while 9edo supposes exactly two interval sizes.
