In this post we will talk about scales.

First be sure you fully understand distance between notes
What is a scale?
A scale is a set of different notes within an octave.
The C major scale
Play all the white notes from C to C: C - D - E - F - G - A - B - C
The distances: C to D: 1 whole-tone / D to E: 1 whole-tone / E to F: 1 semi-tone / F to G: 1 whole-tone / G to A: 1 whole-tone / A to B: 1 whole-tone / B to C: 1 semi-tone
The major scale construction
The pattern is: 1 - 1 - ½ - 1 - 1 - 1 - ½
Applying this to D gives us: D - E - F♯ - G - A - B - C♯ - D
Now that we know the rules to construct a major scale, let's construct all of them...
