i'm confused about something on some of the tabs i find. i copy part of one so you can see what i'm talking about.

Verse 1
-------3x------- -------4x-------
H |x-x-x-x-x-x-x-x-|x-x-x-x-x-x-x-x-|x-x-x-x-x-x-x-x-|
S |----o-------o---|----o-------o---|----o-------o---|
B |o-------o-------|o-------o--o----|o-------o-------|


okay you see the -----3x---- and 4x does that mean i play that a total of 3 times? and is it just the section where the bars are start and end? and do i play that little section 3x before i move on to the middle and then 4x part, or do you do play the whole line 3 times?
