'''Slendro''' is a [[tuning system]] used in Indonesian gamelan music. It provides an octave-repeating pentatonic [[scale]], although ~~the~~ [[~~octave stretch~~|octaves are usually stretched]] to produce complex beating patterns known as ''ombak''.

'''Slendro''' is a [[tuning system]] used in [[Indonesian]] gamelan music. It provides an octave-repeating pentatonic [[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 slendro are numbered 1 2 3 5 6. Tuning varies between gamelan, but most modern Javanese sets encountered in North America seem to be a familiar major pentatonic scale with 3 as the "tonic," but with considerable equalization in the direction of [[5edo]]. However, it's important to note that Slendro is not exactly 5edo, despite being accurately approximated by 5edo.

However, it's important to note that Slendro is not exactly 5edo, despite being accurately approximated by 5edo, since in practice the five intervals are all slightly unequal.

Traditionally, there are three ''pathet'' or modes of slendro. ''Slendro manyuro'' emphasizes 2 and 6 with an "enemy tone" of 5, and ''slendro songo'' 5 and 1 with an enemy tone of 3. Enemy tones are pitches that elaborating instruments generally avoid emphasizing. Finally, ''slendro nem'' is a "miscellany" term that may contain any mixture of slendro manyuro and slendro songo. Most slendro nem pieces are not traditional court gamelan works.
