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.
Synthetic scale By adding a G to the scale, one would end up with the LydianVII, the fourth degree of the Melodic Minor scale. The pitches of synthetic scales may duplicate pre-existing scales, though their derivation is different and their use is often quite different. Synthetic scale In music, a synthetic scale is a scale that derives from a traditional diatonic major scale by altering of one degree by a semitone in either direction. Composer Ferruccio Busoni originally explored these scales in his "A New Esthetic of Music" and their number and variety were later clarified by J. Murray Barbour, who also
