[left]Lesson 2: Positioning
How to Hold Your Guitar
Now that we know a little bit about the different parts of the guitar, lets start by going over how to position yourself best for playing.
Start by finding an armless chair to sit in. Make sure that you're sitting comfortably and that your back is well supported. Also make sure that you have plenty of room on either side in which to move your arms and hold your guitar.
Place the guitar in your lap with the back of the instrument facing (or even touching) your chest. Let the body of the guitar rest on the leg farthest away from the headstock. If you are right-handed, the headstock should be to your left, which means that you will rest the guitar on your right leg. Most acoustic guitar bodies will have curved indentions on either side that are perfect for resting the guitar on your leg.
Take a look at the strings on the guitar. If you are holding it correctly, the thickest string (or 6th) should be closest to your chest, while the thinnest (or 1st) string should be closest to your feet.
Take your fretting hand (left for right-handers and right for left-handers) and grip the neck of your guitar gently. Your thumb should be resting behind the neck of the guitar, supporting your hand while your other fingers float above the strings, ready for action.
Take your picking hand (the one closest to the bridge of the guitar) and grab yourself a pick. Place it between your thumb and index fingers and hold it so that it is secure.
In order to get the feel for what playing guitar is going to be like, start by practicing holding down various notes with the fingers on your fretting hand, and also by strumming or playing individual strings with your picking hand.
(Note: This will invariably sound bad and not at all like real guitar playing, but don't worry, that's not the point right now.) and you can use this website to see some of vidieos http://www.mahalo.com/How_to_Play_Guitar_for_Newbies
