Pull offs.

A Pull off is the Opposite of Hammer on. For example:  To Pull off Put your 1st Finger (Index, Pointer) on 5th fret of the 3rd string, and your Ring finger (3rd finger) on the 7th fret on the same string. Now pluck the string to hear the note of 7th fret, when 7th fret note is ringing remove your ring finger away from the fret in sideways motion. You will hear the pull off sound. During this process put the downwards pressure on both fingers then remove your third finger. Practise to master this technique.
