Major scale will generally reflect the accidentals in the corresponding major scale. For instance, if a piece of music is in E major, then the seven pitches in the E major scale (E, F, G, A, B, C and D) are considered diatonic pitches, and the other five pitches (E, F/G, A, B, and C/D) are considered chromatic pitches. In this case, the key signature will have three flats (B, E, and A). The figure below shows all 12 relative major and minor keys, with major keys on the outside and minor keys on the inside arranged around the circle of fifths.
Yo scale A - B. This is illustrated below. The Ryūkyū scale appears to be derived from the yo scale with pitches raised. 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 "min'yō" scale used in folk music, and whose pitches are equivalent to the second mode of the "yo" scale: Yo scale The "yo" scale, which does not contain minor notes, according to a traditional theory is a pentatonic scale used in much Japanese music including
