The Major Scale
The major scale is a series of 8 notes in alphabetical order that has the familiar sound:
The C major scale contains the following notes
The distance between each two consecutive note is two frets on the same string except for 
and 
where the distance is only one fret. The distance of two frets is called a tone, indicated by T. The distance of one fret is called a semitone, indicated by ST. The first note and last note of a major scale always have the same name. In the C major scale the distance from the lowest C to the C note above it is one octave (8 notes). The following example is one octave of the C major scale.
Each of the 8 notes in the major scale is given a scale number, or scale degree.
The distance between two notes is called an interval. In any major scale the interval between the 3rd to 4th note and the 7th to 8th note in the scale is one semitone (1 fret) apart. All other notes are one tone (2 frets) apart.
The following diagram shows all the notes in the open position. They are all notes of the C major scale, even though the lowest note of the pattern is E and the highest note is G. The key note (root note) C occurs twice and is indicated with a square around it. This pattern can be described as the full open position fingering of the C major scale.
