The 5 positions of the penta range

Learning the 5 positions of the pentatonic scale is a very good starting point for improvisation. You should definitely start with the first course.”My first improv“. This is the range that the majority of guitarists use, because it is easier to use. In almost all the solos you like, it is present. A few details ready that sometimes make all the difference. Let's say that most of the time a base penta scale is used with additions of other notes; either the 2 notes which were removed from the penta, or notes belonging to other keys. Obviously depending on the harmonic possibilities, therefore the degrees of the chords. We will see all this in the Modes.
The pentatonic scale has 5 notes, it is taken from the major scale which has 7 notes.
The 2 notes removed from the major scale to obtain the pentatonic scale (called minor) are the fourth (4th) and the seventh (7th). This is how if we take the notes of the major scale:

1  2  3 (4) 5  6 (7)
