# Natural minor scales explained on a virtual piano

A natural minor scale is a sequence of notes x1,x2,x3,x4,x5,x6,x7,x8 such that

x2 is 2 semitones higher than x1
x3 is 1 semitone higher than x2
x4 is 2 semitones higher than x3
x5 is 2 semitones higher than x4
x6 is 1 semitone higher than x5
x7 is 2 semitones higher than x6
x8 is 2 semitones higher than x7

Alternatively, treating notes as integers, (x1,x2,x3,x4,x5,x6,x7,x8) is a natural minor scale iff (x1,x2,x3,x4,x5,x6,x7,x8)=(x1,x1+2,x1+3,x1+5,x1+7,x1+8,x1+10,x1+12).

Note that the A natural minor scale is the only natural minor scale composed entirely of white keys. Other natural minor scales contain at least one black key.

Note that each natural minor scale contains two minor triads and one major triad:
The first minor triad is composed of the 1st, 3rd, and 5th steps while the second minor triad is composed of the 4th, 6th, and 8th steps.
The major triad is composed of the 3rd, 5th, and 7th steps.
In the A natural minor scale, the two minor triads are: A,C,E and D,F,A, while the major triad is C,E,G.
