The A natural minor scale is:
\override Score.TimeSignature #'stencil = ##f
\relative c" {
 \clef treble \key a \minor \tempo 4 = 360 \set Score.tempoHideNote = ##t \time 7/4
 a4 b c d e f g a g f e d c b a2
</score>
Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. The A harmonic minor and melodic minor scales are:
\override Score.TimeSignature #'stencil = ##f
\relative c" {
 \clef treble \key a \minor \tempo 4 = 360 \set Score.tempoHideNote = ##t \time 7/4
 a4^\markup "A harmonic minor scale" b c d e f gis a gis f e d c b a2
</score>
\override Score.TimeSignature #'stencil = ##f
\relative c" {
 \clef treble \key a \minor \tempo 4 = 360 \set Score.tempoHideNote = ##t \time 7/4
 a4^\markup "A melodic minor scale (ascending and descending)" b c d e fis gis a g! f! e d c b a2
