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
Minor scale Minor scale In music theory, the term minor scale refers to three scale formations – the natural minor scale (or Aeolian mode), the harmonic minor scale, and the melodic minor scale (ascending or descending) – rather than just one as with the major scale. \override Score.TimeSignature #'stencil = ##f \relative c' { </score> \override Score.TimeSignature #'stencil = ##f \relative c' { </score> \override Score.TimeSignature #'stencil = ##f \relative c' { </score> In each of these scale formations, the first, third, and fifth scale degrees form a minor triad (rather than a major triad, as in a major scale).
