How to play guitar (Continued)

Last week we went over the different parts of the guitar, lets start this week off now 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. No slouching! Place the guitar in your lap with the back of the instrument touching your chest. Let the body of the guitar rest on the leg farthest away from the head. If you are right handed, the head should be to your left, meaning you have to place the body on your right leg. If you look at the neck of your guitar you can see the thinnest string is closer to the ground.
Another of the most important things you will need to do in order to keep your guitar sounding good is to tune it on a regular basis. Tuning is done by tightening or loosening each of the tuning pegs on the head of the guitar. Here is how it's done. First place a finger on the 5th fret of the 6th string and play the note. Next play the 5th string open. When in tune, these two notes should sound exactly the same.Turn the peg for the 5th string until they sound the same. Notice that when you turn the peg one way the note gets higher. High notes are Sharp notes, and low notes are flat notes. Next place your finger on the 5th fret of the 5th string and repeat this process with the 4th string open. After you have done that repeat this process for the 4th and 3rd strings. Now instead of placing your finger on the 5th fret of the 3rd string when adjusting the 2nd string, place it on the 4th fret. Finally to tune the 1st and final string, go back to the first method by playing the 5th fret of the 2nd string.
That's all for this session, and I will continue my how to on how to play guitar in another week.
