After you have learned a solo in one of the five forms, the next step is to move your favourite licks (or the whole solo) to each of the other forms in the same key. You will often have to change the fingerings and also the techniques (e.g., substitute a hammer-on for a bend) but it is usually possible to play any lick in all 5 forms. For example, take the opening lick from the solo in lesson 9, which is only 3 notes.
Here it is in the E form in the higher octave. As mentioned before, the fingering often changes when moving a lick from one place on the fretboard to another.
Here is the same lick played in the D form.
This is the same lick in the higher octave of the D form.
Get the idea? This is really worth doing because it enables you to play equally well all over the fretboard and often leads to new ideas. For example, if you play this lick in the G form at the 2nd position (fret) you cannot do a downward trail off from the A, but you could make it go up instead.
Next you could play the lick again in the higher octave of the G form with an upward Trail Off. Then you could try playing it in any of the other forms in the same way.
