“Today I want to talk a little about music theory”, says Johnson, “music is mathematical and the fret board is like a grid”. Claude starts off this theory guitar lesson by talking about the intervals between frets being referred to as half steps and whole steps, which he explains as one fret is a half step and two frets is a whole step. Johnson continues by demonstrating and explaining the intervals in the minor pentatonic scale and the major scale. Claude explains that chords can be constructed based on the intervals of a scale and plays some demonstrations of this concept. Claude says that he covers this in more detail in his course “Ultimate Beginner Guitar Course” which is available at

The major scale, aka the Ionian Mode, is a seven tone diatonic scale that is widely used in western music. The eighth duplicates the first at double its frequency so that it is called a higher octave of the same note, which its name is derived from Latin "octavus", the eighth.

The Pentatonic Scale is a musical scale with five notes per octave. They can be found all over the world and are the main scale used in the Blues genre.
