Welcome to your first guitar lesson. This lesson will be a step by step guide for anyone that wants to learn the guitar and has never played before.
First thing to do is to tune the guitar. We will tune to A = 440HZ which is standard tuning.
If you don’t have a tuner you can use this link here

Ok so now we are in tune , next lets learn the basics.
Learn 1 The String Numbers
2 String Names
3 Fret Numbers
4 Left Hand Finger Numbers
5 Right Hand Finger Names
How To Hold A Pick
Check out the right way to hold a pick, and don’t worry if you don’t want to use one, you can strum with your thumb. But give it a try , ..its good to be able to do both.
These chords are intro chords only , you wont need them in the future They are designed to get you playing fast and also to introduce you to the full versions later on .If you find this intro stuff too easy , don’t worry , it will get more involved I promise.
So you will notice on the chord charts not to play strings 5 and 6 for all three intro chords G,G7 and C .
Each diagonal line represents one down strum.
Each chunk of four strums represents one bar , which in this case is one bar of 4/4 timing.
4/4 timing means there are 4 beats to every bar .
First Chord Easy G
Slowly strum strings 4321 on easy G with down strums and position your third finger as in the picture. Notice I am using pretty much the tip of my third finger. Also I am only using the amount of pressure needed to make the chord clear.
Keep it simple slow and steady and in two lots of 4 with no pauses in between. Enjoy the sound you are making,…you are making music , allow yourself to feel good about this! This is fun huh,…lets go to the next chord.
Easy G7 
Now with your first finger go to the easy G7 , same deal two lots of G7 using your first finger positioning like the photo .
Ex 1
Strum this exercise with no pauses even on changing to G7 and back to G.
Easy C Chord
This chord involves two fingers and you will quickly realize that the angle of how your fingers are placed is important.see photo . 
Exercise 2
Now we add the Easy C chord to the mix . Same as Ex 1 only there is a C chord on the 3rd line .This is where you will notice things slow down a bit during changes , work on not stopping your right hand strumming to keep your changes smooth .This wont seem like a big deal at the moment but it will become huge when you start to increase your chord repertoire .For this reason I have written a whole article on it .

The name of the game is to keep your right hand moving ,….don’t stop no matter what even if your left hand is not quite in position yet ,…trust me….it will catch up !
Exercise 3 The Sun
Now we get into the real chords , Em or E minor as it is pronounced.
Give it a strum use the fingertips arch so they don’t touch other strings and strum all the strings . Nice sounding chord hey!
Now we introduce the bar line to all the exercises and songs . Think of the space between the bar lines as the bar . There are 4 beats to every bar in this song , the time signature of 4/4 tells us this , and for now the actual beats are written as diagonal lines .
