Editing Scale (music) (section)

===Intra-scale intervals===
Some scales use a different number of pitches. A common scale in Eastern music is the pentatonic scale, which consists of five notes that span an octave. For example, in the Chinese culture, the pentatonic scale is usually used for folk music and consists of C, D, E, G and A, commonly known as gong, shang, jue, chi and yu.<ref>{{Cite journal|last1=Wu|first1=Dan|last2=Li|first2=Chao-Yi|last3=Yao|first3=De-Zhong|date=2013-10-01|title=An ensemble with the chinese pentatonic scale using electroencephalogram from both hemispheres|url= |journal=Neuroscience Bulletin|language=en|volume=29|issue=5|pages=581–587|doi=10.1007/s12264-013-1334-y|issn=1995-8218|pmc=5561954|pmid=23604597}}</ref><ref>{{Cite journal|last=Van Khê|first=Trân|date=1985|title=Chinese Music and Musical Traditions of Eastern Asia|url=https://www.jstor.org/stable/43562680|journal=The World of Music|volume=27|issue=1|pages=78–90|jstor=43562680 |issn=0043-8774}}</ref>

Some scales span part of an octave; several such short scales are typically combined to form a scale spanning a full octave or more, and usually called with a third name of its own. The Turkish and Middle Eastern music has around a dozen such basic short scales that are combined to form hundreds of full-octave spanning scales. Among these scales [[Hejaz scale]] has one scale step spanning 14 intervals (of the middle eastern type found 53 in an octave) roughly similar to 3 semitones (of the western type found 12 in an octave), while [[Saba scale]], another of these middle eastern scales, has 3 consecutive scale steps within 14 commas, i.e. separated by roughly one western semitone either side of the middle tone.

[[Gamelan]] music uses a small variety of scales including [[Pélog]] and [[Sléndro]], none including equally tempered nor harmonic intervals. [[Indian classical music]] uses a moveable [[swara|seven-note scale]]. Indian [[Rāga]]s often use intervals smaller than a semitone.<ref>Burns, Edwaard M. 1998.
