Guitar instruction from a private guitar teacher is by far the best way to learn guitar.
A private guitar teacher will be able to demonstrate fingering techniques and chord progressions, scales and styles.
Private guitar instruction will help you get the most out of your new guitar. A lot of people find playing the guitar to be quite difficult at first and give up before they even have any lessons! Getting over the initial "bump" is critical as playing the guitar is a very rewarding, and fun, hobby.
Once you have mastered one style of playing the guitar there are loads more to try - flamenco, blues, jazz, brazilian, classical, funk, heavy metal etc.
