Guitar tabs represent schematic view for playing the guitar, in which sheet music reading knowledge is not necessary. So, let’s start:
The letters and lines represent the strings
where the bottom line represents the lowest E string, the second line from the bottom represents the A string, etc:
Numbers on the lines denote the frets
In the example below, the tab is telling you to play the second string 5th fret:
When the number 0 is used in guitar tab, than you should play the open string.
If you have the following situation:
you should play all these notes together (you will hear E-major).
Hammer on (h)
If you have following situation:
you should pick the A string 5th fret and hammer on to the 7th fret.
Pull-off (p) is the opposite of a hammer on, so, if the tab is:
you should place one finger (of your left hand) on the E string 6th fret and the other finger on the E string 4th fret. Now you should play string, then remove your finger from 6th fret.
Look at the example below:
This indicates that you should bend the 9th fret (of string B) until it sounds like the 11th fret.
Slides (/, s)
Pick the given note and slide it up or down.
