The minor pentatonic scale - 5 positions
Let's take a look at the minor pentatonic scale. There are 5 common positions on the guitar for this scale. The most common position and the one you should definitely learn first, is position nr 1 below. Try to focus on one pattern/position at a time and don't try to learn all at once.
It is important to get the notes into your head and ears, as well as your fingers. The fingering is just a suggestion and you will notice that you need to be flexible in your fingering when improvising, switching between the positions and bending the notes. To play a position an octave up, move it up 12 frets. After the 5th position you are back to the 1st position again.
