Here are some examples of hand stretches on the fretboard. The first four measures is an exercise I "stole" from Dream Theater's John Petrucci and shows a chord of sort. The sound of the chord is not important but take notice of the stretch between index and middle fingers and the ring and pinky fingers. Check out how the pattern goes. The second measure shows the two middle fingers shifting while the outside fingers maintain their positions. The third measure shows the middle fingers maintaining their positions and the outside fingers shifting opposite of each other but along their same perspective frets. The final measure shows the outside fingers maintaining their new position while the iside fingers shift to their original positions. Try moving these chord shapes to the lower or wider frets. You will feel the stretch. The following two measures shows variations to the original shape with stretches in different fingers. Also play these shapes along four string groups. The advanced variation of this exercise is to insert a fret in between each finger. Example: 10th fret (1st finger), 12th fret, (2nd finger), 14th fret (3rd finger), 16th fret (4th finger). This stretch is for the advanced so please exercise caution before attempting. If you feel and pain, please stop and rest the hands. The chord shapes can be play as a chord or arpeggiated, again the stretch is important. The next group of stretches actually utilizes chords. This is how it looks
. Next is
and last is:
Which goes into a Bmajor 7 chord thus starting the exercise over again. This exercise is to be moved one note at a time and your goal is to get to the first fret with the index finger. Go slow with this one, and feel the stretch. You can play this exercise both chordally and as arpeggios. The last set of stretches should be done along every string and done slowly, holding the stretch. Again, if you feel pain then stop! If these stretches prove to be a bit difficult then modify it to meet your level.
