A pull-off is another technique of sounding a note without actually picking the string (with the pick or the right hand). This time a left hand finger is pulled away from the string after fretting the note. In the following example, only the E note is picked, but the third finger "pulls-off" the string to produce the sound of the D note.
The pull-off effect is indicated by the curved line and the "P" above it. Remember that the second note (D), is not picked; the sound is produced entirely by the third finger pulling-off to the string. You must be very careful with the timing of the pull-off. Both the E and D notes are eighth notes and each should have an equal time value when played (regardless of the pull-off technique).
This example combines the pull-off technique with the hammer-on technique.
