By pulling toward down and moving the wrist, bend the G string a step higher, to D pitch. Repeat this operation until your intonation is good. Once the bent is held, use your right hand in order to attack toward down G string at about 11cm from the tailpiece and touch the string with the top of your thumb while touching the string with the pick. It will give you to same pitches, two octaves higher. By attacking between 8.5cm and 9cm from the tailpiece, you'll get pitches a 3rd higher, at 7.5cm a 5th just above, at less than 7cm a 7th minor above and a bit more than 6cm a third octave.
Harmonic positions vary with freted notes.
Try the most you can on the whole length of the neck to make you feel good. This technique works better on certain strings. About the left hand, you can bend toward down or toward up a 2nd minor, a 2nd Major, a 3rd minor, a 3rd Major or as far as you can. Good luck and enjoy.
