The
Major Scale on Guitar
The major scale should be the first scale you
learn, because when
building chords or other scales, the major scale is the "starting
point". You'll see what I mean as we progress.
I just want to make it clear though - this lesson
is not just about lead guitar. It's about the major scale in its purest
form and how it
appears
across the entire fretboard of your guitar...
It's about using these visual patterns to construct chords,
arpeggios and
other sequences in a particular
key, confidently.
This lesson is your
first rewarding step to
understanding how chords (and therefore, lead harmonies) are built
around the major scale - the very basis of what
many call "western" music.
It's not difficult, it's just
something you need to devote a little time to.
Major scale
intervals and basics
So what makes it a "scale"? -
one word - intervals.
Intervals are the spaces/gaps between
each note in a scale, the separation of tones across a scale.
Hopefully, you've taken the
guitar
fretboard lessons on this site so you'll know how intervals work
on the fretboard, but let's recap specifically for the major
scale...
The major scale starts with
note number 1 (the root note)
and continues in intervals up to note 7. The intervals
are as follows...
1
W 2 W
3 H 4
W 5 W 6
W 7 H 1
W = whole step (or 2 fret interval)
H = half step (or 1 fret interval)
So if you were to play the
major scale starting on the open bottom E string
and played out the intervals on just that one string, this is how they
would appear
("1" being the open, unfretted string)...
1
= the root note, and in this case the
root note is "E".
Therefore this would be the E
major scale, since the root (1) note lies on the the note E.
Once we get to note 7, the
next note is the octave - the same as the root or
note 1, but higher. The scale cycle begins again.
It's that typical "do-re-mi"
scale we're all familiar with and it's where chords and other scales
are built in relation to. So when we
talk about a flat 5th (symbolised as "b5")
in a
chord or scale, we
really mean "the 5th tone of the major scale flattened one half step
from its original position".
That's an important point
actually - when we flatten a note half a step (1
fret) the symbol to represent this is a b
(e.g. flatten the 9th and you get b9)
If you sharpen
(move up one half step/fret) a note you get the #
symbol (e.g. sharpen the 5th and you get #5)
Now, it's necessary to use
more than one string most of the time. So
you have to transfer these scale intervals across the 6 strings of your
guitar.
The most commonly used (and
seen) "boxed" scale pattern for the major scale is...
Remember, 1,
the first note of the scale is the root
note, so if
you started the scale at fret 3 on the low E
string, the 1st note would be G
so it would be the G major
scale.
You should learn
that major scale pattern above to start with and learn the visual
relationships and intervals between the notes.
For example:
-
the second occurrence
(octave) of the root note appears on the D
string two frets above the 1st root note
-
the third occurrence (even
higher octave) of the root note appears on the high E string
on the same fret
as the 1st root note!
-
the second occurrence
(octave) of the 5th appears on the B
string two frets below the 1st occurrence of the 5th note.
-
the 3rd
appears one fret left of the lowest root note on the A string AND a
higher 3rd (octave) appears one fret left of the root's octave on the G
string.
See if there are any other visual
relationships you
can pick out.
Once you've learned that boxed
scale shape you should move on to learning other positions of the major
scale - I call these ascending and descending
shapes depending on which direction the scale pattern travels on the
fretboard.
Try to learn scale shapes
wherever chord shapes
may occur, as the two essentially draw from the same selection of notes.

Other
major scale shapes/positions
Remember: these are all exactly the same major scale as above, with
exactly the same intervals, they just use different areas of
your guitar's fretboard and make use of different strings for
different notes as a result.
They can be seen as formed
around various chord shapes (e.g. D shape barre, C
shape
barre etc.)
1 = root note for whatever key
you're playing in (you can shift these shapes up and down the fretboard
depending on the chord/key you're playing around.
So above we
learned the E
string root - "boxed" major scale...
E string root -
descending
Used to construct chords
around the G shape.

E string
root - ascending
Used to construct chords
around the E shape.

A
string root - boxed
Used to construct chords
around A shape.
So this time, same scale, same
intervals but starting with the root on the A string.

A
string root - descending
Used to construct chords
around the C shape.

A
string root - ascending
Used to construct chords
around the A shape.

D
string root - boxed
Used to construct chords
around the D shape.
Again, same scale and
intervals but starting on the D string (where even higher voiced, 4
string chords can be built from)...

D string root - descending
Can be used for constructing
higher voiced, 4 string chords which have a D string root.
Arrrgh! Making sense
of it all!
At the beginning of this
lesson I stated this wasn't only
about lead guitar, but rather the
theory behind building chord harmonies, which lead
guitar does fall under. I want you to understand that chords and scales
are pulled from the same pot of tones.
When you build a chord from a
scale, you get a chord shape.
This is where the E, A, C, D
and G chord shapes come from, and
you can use the assigned scale shapes above to construct chords around
these positions which in turn gives you several different chord voicings
to experiment with.
For now though, just make sure
you learn these positions and shapes for
the major scale. The same "shape" technique can be applied to other
scales as and when you come to them.
Thanks for working through
this - we've covered some good ground here :)
Hope to see you soon!
