The yo scale, which does not contain semitones, according to a traditional theory is a pentatonic scale used in much Japanese music, excluding gagaku and Buddhist chanting. The yo scale is used specifically in folk songs and early popular songs and is contrasted with the in scale which does contain semitones.[1] The In scale is described as dark while the yo scale is described as 'bright' sounding.[2]

It is defined by ascending intervals of two, three, two, two, and three semitones. An example yo scale, expressed in western pitch names, is: D - E - G - A - B. This is illustrated below.

More recent theory[3] 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 min'yō scale used in folk music, and whose pitches are equivalent to the yo scale[4]:

The Ryūkyū scale appears to be derived from the yo scale with pitches raised.[6]
