I'm tired of making music tabs so I thought I'd perhaps share with
you guys some music theory. For this "lesson", I'll be explaining
the pattern for a music scale. As you already know, a scale is a
selection of notes within an octave. There are different kinds of
scales (major, minor, etc.), but I'll be discussing the major
scales right now. A major scale is constructed with the following
pattern:

W — W — H — W — W — W — H

W: whole step
H: half step

You can pretty much build any MAJOR scale using that pattern.
Some examples...

C Major scale.

     C  D  E  F  G  A  B  C
G:——————————————————2——4——5———
D:—————————2——3——5————————————
A:———3——5—————————————————————
E:————————————————————————————

As you can see...

C: root
D: whole step from C
E: whole step from D
F: half step from E
G: whole step from F
A: whole step from G
B: whole step from A
C: half step from C


Next, we will try an Eb Major scale.

     Eb F  G  Ab Bb C  D  Eb
G:——————————————————5——7——8———
D:—————————5——6——8————————————
A:———6——8—————————————————————
E:————————————————————————————

Again...

Eb: root
 F: whole step
 G: whole step
Ab: half step
Bb: whole step
 C: whole step
 D: whole step
Eb: half step


Lastly, a D Major scale.

     D  E  F# G  A  B  C# D
G:——————————————————4——6——7———
D:—————————4——5——7————————————
A:———5——7—————————————————————
E:————————————————————————————

Yeah, you got it.

 D: root
 E: whole step
F#: whole step
 G: half step
 A: whole step
 B: whole step
C#: whole step
 D: half step


And that's it...
