In scale


The in scale is, according to a traditional theory, one of two pentatonic scales used in much Japanese music, excluding gagaku and Buddhist chanting. The in scale, which contains minor notes, is used specifically in music for the koto and shamisen and is contrasted with the yo scale, which does not contain minor notes.
More recent theory emphasizes that it is more useful in interpreting Japanese melody to view scales on the basis of "nuclear tones" located a fourth apart and containing notes between them, as in the miyako-bushi scale used in koto and shamisen music and whose pitches are equivalent to the in scale:

''In'' scale in the other musical traditions

In Indian classical music, Gunkali and Karnataka Shuddha Saveri are nearly identical to the pentatonic in scale, highlighting the shared past of their origins. Some rare examples of ancient genres of Andean music use a scale similar to the in scale combined with melody leading with a parallel fifths and fourths. For example listen to Machulas Kantu by Bolivia Manta folk group.
