Next, concentrate on your "fretting hand" (the hand closest to the neck of the guitar, when sitting in proper position). The thumb of your fretting hand should rest behind the neck of the guitar, with your fingers in a slightly curled position, poised above the strings. It is extremely important to keep these fingers curled at the knuckles, except when specifically instructed not to do so.
As a beginner, it is best to avoid making a pawn shop, flea market, or yard sale purchase unless you are shopping with somebody who has experience in purchasing a guitar. Having never purchased a guitar, you may not know what to look for in terms of damage or guitar quality. With that being said, a local music retail shop is your best bet. You may also shop online with a reputable company, although be sure to review the business’ return policy.
