Holding the Guitar
Whether sitting or standing and using a strap, the guitar should be in roughly the same position. Despite what you see some guitarists in rock bands doing, the guitar is much harder to play when it’s hanging at your knees. Consider the type of music coming out of that guitar before you model your technique after the person holding it!Note: This article will assume you play the guitar right handed, meaning your left hand pushes down on the strings and your right hand holds the pick or plucks the strings.
Every beginner’s guide to the guitar is going to start out telling you how to hold the instrument. My general advice is to first pretend that you are holding a guitar and pay attention to where your hands, wrists, elbows and arms line up with your body. The guitar should rest comfortably within the natural posture of your body. If it feels wrong, it’s probably wrong.
Tip: Sit down in a comfortable chair, sitting up straight with your shoulders in line with your hips and your knees straight in front of you, relaxed so they are slightly open. Let your left hand hang at your side, completely relaxed. Now bend at the elbow, raise your hand, and rotate your wrist so that your palm is facing nearly up. Your left hand should be almost over your left knee. There should be a slight curve to your fingers and thumb. The neck of the guitar should pass through your hand in this position comfortably. If you were to look down at yourself from a birds-eye view, the guitar will be at an angle, only touching your right leg and the right side of your stomach.
The exact position of your right arm will vary based on the size of the guitar and guitarist. The only advice I can give without seeing you hold the guitar in person is make sure you are not contorting your shoulder or elbow to reach over the top of the guitar. This is especially true for smaller body types playing larger acoustic guitars. To compensate, bring your left elbow forward, pushing the neck a little further from your body so the body of the guitar pivots back under your arm a little more. You’ll have to get used to not being able to see all the strings when you look down.
