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.
Start off figuring out what style you are looking for. Is it acoustic or electric? What music styles are you looking for? From country and bluegrass all the way to heavy metal and rock, there are so many different styles of guitar music. If you are just starting out and are not sure what to begin with, this is okay. Some instructors are very good at teaching beginners and helping them find out what they are passionate and good at. If you do know what you are interested in, the best thing to do is to find an instructor that teaches that style. On Lessons.com you can do this by reading through the teacher’s description.
Learn how to transition to different chords. One way to become proficient quickly is to learn how to transition between the various chords quickly. These transition periods are often the hardest for beginners to play when they are starting off. The more you practice between switching to different chords, however, the better you'll get at doing it in songs. Practice switching between open chords like G, A, E, and C. 
Position your fingers on the neck. The dots on the chords represent where you should hold down your fingers on the neck. For instance, an A major is played by holding down the string on the second fret on the 2nd, 3rd, and 4th string. An E minor is played by holding down the second fret on the 5th and 4th string. Hold the strings down until they are pressed against the neck of your guitar.
