Ex. 1 - Let's start our next lesson with learning what an 
pull-off is. Pull-off is another kind of legato playing 
because we are picking only first note in sequence. 
Pull-offs are marked by arches in music (just like 
hammer-ons). To play the first example you have to put 
your index finger on 3rd fret of high E string and pick 
this note. Now you have to make a pull-off. To do it you 
have to quickly lift your finger from the 3rd fret - open 
string ("0") should sound with its full power ;) Then you 
have to pick an open string. After doing that - pick the 
note that you can find on the 5th fret, make a pull-off 
and so on...

"P" means "Pick"
"PO" means "Pull-off"

Ex. 2 - "Start off with both finger on the fretboard. The 
index finger at the 5th fret of the D string, and the ring 
finger on the 7th fret. Just pick the note at the 7th fret. 
While that note is ringing, pull-off your ring finger and 
leave your index finger on the 5th fret so the G note 
sounds."

Ex. 3 - Practice :)

Ex. 4 - We can connect Hammer-ons with Pull-offs. 
Listen to the example then play it by yourself. Guitarists 
often connect those two techniques in their solos.

Ex. 5 - In this example you have to make a bend. I'll 
write more about this technique soon. In this part of 
school I will tell you only a few things about it. To make 
a bend that is shown in this example (it is marked with 
a little arrow) you have to put your index finger on the 
second fret of the G string, pick the note and bend the 
string with that finger. After that get the string to its 
normal position without lifting your finger. The bend 
should send exactly like the one shown in this example. 
And that's all :) Practice!

Ex. 6 -  Look at this. We can add a second or ninth to 
basic Power Chords. If we will add a ninth to a C5 
Power Chord we will get C5add9 Chord. If we will add 
an ninth to D5 Power Chord we will get a D5add9 
Chord and so on... In 18th bar you can find an A5add9 
and C5add9 Chords, in bar 19th you can find D5add9 
Chord. In 20th bar you will find C5add9 Chord again 
(remember that "add9" = "sus2" ("C5add9" = 
"C5sus2")).

Ex. 7 - We can modify basic Power Chords by adding a 
fourth to them also. We are adding an "sus4" to names 
of that Chords. In first bar of this exercise you'll find and 
Dsus4 Chord, in second bar Asus4, in third bar Esus4 
and in fourth bar Asus4 again.
