Minor scale based on the accidentals of the "natural" minor scale, not on those of the harmonic or melodic minor scales. For example, a piece in E minor will have one sharp in its key signature because the E natural minor scale has one sharp (F). Major and minor keys that share the same key signature are "relative" to each other. For instance, F major is the relative major of D minor since both have key signatures with one flat. Since the natural minor scale is built on the 6th degree of the major scale, the tonic of the relative minor is
G-flat major of his most popular compositions, "La fille aux cheveux de lin", the eighth prélude from his "Préludes, Book I" (1909-1910). G-flat major G-flat major (or the key of G) is a major scale based on G, consisting of the pitches G, A, B, C, D, E, and F. Its key signature has six flats. Its relative minor is E-flat minor (or enharmonically D-sharp minor), and its parallel minor is G-flat minor, usually replaced by F-sharp minor, since G-flat minor's two double-flats make it generally impractical to use. Its direct enharmonic equivalent, F-sharp major, also contains the same number of sharps.
