Price Tag tab by Jessie J (Ver. 3)

Through this song the same chords are played over again(F, Am, Dm & Bb)
In the background you would here this:

e--13---12---13---10-----|
b--13---13---15---11-----|
g--14---14---14---10-----|
d------------------------|
a------------------------|
E------------------------|

During B.o.B's part there is a little riff that goes like this:

Slide
e--13--15-17--15-13 -12----15--11 -10--13--10 -10---------------|
b--13-------------- -13----13---- -10--10---- -11--------11--11-|
g--14--15-17--15-14 -14----14---- -10--10---- -10--Slide-10--10-|
d------------------ ------------- ----------- -----10-12---12---|
a------------------ ------------- ----------- ------------------|
E------------------ ------------- ----------- ------------------|

Also while playing throught this song it sounds really good making up solos using the F
Major Pentatonic shown below.

e---------------------------10-13-|
b---------------------10-13-------|
g---------------10-12-------------|
d---------10-12-------------------|
a---10-12-------------------------|
E-13------------------------------|

I hope this helps.
