How to use and practise it
Learn Box 1 until you can play it without looking, then add Box 2 above it. Bend the 4th up to the 5th and the minor 7th up to the root: those two bends are the sound of rock guitar.
Same notes, another root: F major pentatonic. The shapes on the neck are the same; only the note you start and end on changes.
The blues scale adds one note, the flat five, between the 4th and the 5th. Compare the two: D blues.
Set the tempo low, play each position up and down with the button above, then try it yourself at the same speed. Raise the tempo by 4 BPM only when it is clean.
