but seriously.. You need to understand the Chromatic Scale, that is the scale that has ALL the notes in it. The C Major scale is only 7 notes (or 8 if you include the note that is exactly one octave higher than that starting note). The Chromatic scale has 12 (13 if you include the note that is exactly one octave higher than that starting note). That's a whole other 5 notes!!!
The Chromatic scale starting on an "A":
1<=------A-----=>Root/Tonic
2<=------A#----=>Minor 2nd
3<=------B-----=>Major 2nd
4<=------C-----=>Minor 3rd
5<=------C#----=>Major 3rd
6<=------D-----=>Perfect 4th
7<=------D#----=>Diminished 5th
8<=------E-----=>Perfect 5th
9<=------F-----=>Minor 6th
10<=------F#----=>Major 6th
11<=------G-----=>Minor 7th
12<=------G#----=>Major 7th
Now.. you will want to have a look at lessons about "Intervals" or look at them again while considering the above chromatic scale. When they teach about intervals they talk about Whole Steps (WP) and Half Steps (HS). The above scale is all Half Steps between each note. A Half Step is equivalent to ONE fret on your guitar. When they talk about Whole Steps, they are talking about moving TWO frets. A Whole Step in relation to the chromatic scale above would move 2 notes, either up or down the scale.
Sooo.. now when they say that the Major Scale is made up of the following "Interval Pattern": WS, WS, HS, WS, WS, WS, HS.. what they mean should make more sense. Without knowledge of the "in-between" notes.. the other notes don't make a lot of sense by themselves. Let's take a look at two Major scales.. I'll pick C Major (because it's easy to write out and you already know it) and G Major (because it is just as easy to write out.. lol..):
C Major Scale
C <=-- Root --=>
Whole Step
D <=-- Major 2nd
Whole Step
E <=-- Major 3rd
Half Step
F <=-- Perfect 4th
Whole Step
G <=-- Perfect 5th
Whole Step
A <=-- Major 6th
Whole Step
B <=-- Major 7th
Half Step
C <=-- Octave (Root)
G Major Scale
G <=-- Root --=>
Whole Step
A <=-- Major 2nd
Whole Step
B <=-- Major 3rd
Half Step
C <=-- Perfect 4th
Whole Step
D <=-- Perfect 5th
Whole Step
E <=-- Major 6th
Whole Step
F# <=-- Major 7th
Half Step
G <=-- Octave (Root)
Oh heck.,. let's do the A Major scale too..
A Major Scale
A <=-- Root --=>
Whole Step
B <=-- Major 2nd
Whole Step
C# <=-- Major 3rd
Half Step
D <=-- Perfect 4th
Whole Step
E <=-- Perfect 5th
Whole Step
F# <=-- Major 6th
Whole Step
G# <=-- Major 7th
Half Step
A <=-- Octave (Root)
So you see.. that Intervals mumbo-jumbo actually does make sense.. This naming convention stuff also starts to make sense in other lessons, such as chord progressions and chord creation.
But yeh.. it really helps if you have more structure in your lesson plan.. I'm glad that GT is aware of this problem as is doing something to address it.
