Finding easy guitar tabs to get started, can be a bit frustrating.
Probably the easiest is 'The Star' or to give its full name, Twinkle, twinkle, little star.

If you do not remember it or never herd it before it goes like this.

Twinkle, twinkle, little star,

How I wonder what you are!

Up above the world so high,

Like a diamond in the sky.

Twinkle, twinkle, little star,

How I wonder what you are!

Very basic but a great place to start out. So we shall now get going.
Using a tab or to give it its full name,tablature,we shall not require sheet music for this. We shall use the thinnest three strings for this as that is all we need for this particular so

This is abbreviated run through.

Staring with the string with the highest pitch,E. This is also know as the first string. On the tab this will be at the top on the left shown as a 1.

Play the first string four times without pressing down any finger on your right hand. That is no frets at the start,otherwise known as an open string. Please note when you look at the tab this is represented as 0. No frets are used. so four timers will look like this. 1 the string and 0,0,0,0.No frets used.

Next second string, shown as a 2, play this four times. Pressing down your first finger on the first fret. This is represented on the tab as a 1. That means your pressing down on the first fret. So once again four times, that will look like this, the second string 1,1,1,1. First fret used.

Then, play the third string, four times while pressing down the string on the second fret. Can you guess how that will be shown?
Well like this,a three for third string and four twos. The two represents the second fret and is played four times.

OK ready? Now play the first notes of Twinkle, Twinkle, Little Star with guitar tab.
After having played this part twice, go back and play the first guitar tab part and the melody is complete.

Hurray you have done it! You can now go looking for more easy guitar tabs.

I wish you every success.
