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
D-flat major D-flat major D-flat major (or the key of D-flat) is a major scale based on D, consisting of the pitches D, E, F, G, A, B and C. It is enharmonically equivalent to C-sharp major. Its key signature has five flats. The D-flat major scale is: \override Score.TimeSignature #'stencil = ##f \relative c' { </score> Its relative minor is B-flat minor. Its parallel minor, D-flat minor, is usually replaced by C-sharp minor, since D-flat minor features a B in its key signature and C-sharp minor only has four sharps, making it rare for D-flat minor to be used.
