A scale is simply group of notes that has a specific sound. The major scale has a happy sound. It ascends via steps going up and then down.
The C major scale consists of these notes: C D E F G A B C Try and play this on the guitar.
The scales are made up of intervals (the distance between the 2 notes)
These intervals are semitones (1 fret distance) and tones (2 fret distance).
The formula for major scales is:
Tone Tone Semi-tone Tone Tone Tone Semi- Tone
You could play a major scale using this method on any string of the guitar without know the notes. Give it a try on the high E string.
You would play these frets on the string 0 2 4 5 7 8 9 11 12. If you played it on the E string you would have just played the E major scale.
Try playing it on some of the other strings. The notes that you start on is called your root note that give the scale the name whether it's A major, D major etc.
The major scale has 7 notes we give each of these notes interval names.
These are:
Root
Major 2
Major 3
Perfect 4th
Perfect 5th
Major 6th
Major 7th
Seconds, thirds, sixths and sevenths are either major or minor and fourths and fifths are either perfect, diminished or augmented.
We sometimes have other names for these intervals:
We sometimes call minor intervals flats therefore a minor 3rd could all be called a b3.
Diminished means to make smaller so a diminished 5th could also be called a b5.
Augmented means to make bigger so a Augmented 4th could also be called a #4
Below is a diagram of 5 major scale shapes in the key of G. These shapes cover all the notes in G major on the fretboard in 5 easy to learn shapes.
Each of these shapes in linked with a chord. Click here for the CAGED Chords
These shapes can be put into any different key. The red notes are the root notes. If you were to play position 1 starting on the 8th fret you would be playing the C major scale.
Start by learning positions 1 and 4. Start by playing from the root note.
In position 1 play from the 3rd fret on the low E string
In position 4 play from the 10th fret of the A string.
Played the relevant CAGED chord before you play the scale.
Play it with a metronome nice and slowly to begin with, gradually speeding it up - this is great for building technique!
Sing the scale. This really help you understand the sound of the scale.
Improvise with the scale using the backing track below

Try playing the scales in a different key for this you need good fretboard knowlege
