The in scale (also known as the Sakura pentatonic scale due to its use in the well-known folk song Sakura Sakura) 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 semitones, is used specifically in music for the koto and shamisen and is contrasted with the yo scale, which does not contain semitones.

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:
scale on D, equivalent to in

In scale in the other musical traditions 
Some rare examples of ancient genres of Andean music (e.g. k'antu) use a scale similar to the in scale combined with melody leading with a parallel fifths and fourths. For example listen Machulas Kantu by Bolivia Manta folk group (Wiñayataqui, 1981).
