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 note is two frets except for and
where the distance is only one fret.
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.
