The Minor Scale
From “The Minor Scale Pattern¨ in Music Theory for Electronic Music Producers
Remember the pattern for the major scale? It looked like this:
W W H W W W H
In this pattern, ‘W’ refers to whole-step and ‘H’ refers to half-step.
Everything about this is the same in a minor scale, except the order of the half-steps and whole-steps. In a minor scale, the pattern is this:
W H W W H W W
A C (natural) major scale, i.e. a major scale pattern in the musical key of C, looks thus on the standard Western classical piano keyboard (refer to 20240904103821-Musical_Scale_and_Key_Patterns):

However, the A (natural) minor scale, i.e. the minor scale pattern in the musical key of A, would lead to this result when implemented on the standard Western classical piano keyboard:

Another way to create a musical scale describable as minor, aside from simply implementing the scale’s interval pattern (refer to 20240901171406-Musical_Intervals), is “to start with a major scale, and adjust the notes that are different¨ (Allen 2018, 119). There are three notes that differ for the minor scale (Ibid):
From “Minor vs. Major¨ in Music Theory for Electronic Music Producers
The third is a 1/2 step lower in the minor scale. Just like how we lowered the third of a major chord to make it minor, we lower the third note in the major scale to make a minor scale. The second note that is altered is the sixth. It is also lowered by a 1/2 step. Remember that the sixth is the inversion of the third, so it also has some authority over the major/minor quality. Last, we lower the seventh a 1/2 step as well.
To sum up (Ibid):
- A minor scale has the third a half-step lower than in the major scale
- A minor scale has the sixth a half-step lower than in the major scale
- A minor scale has the seventh a half-step lower than in the major scale
A simpler way of putting it is that (Ibid):
From “Minor vs. Major¨ in Music Theory for Electronic Music Producers
A minor scale can be said to be a: “major scale with a b3, b6, and b7¨.
