If you're confident finding frets and strings quickly, you can move past this step and onto reading tabs. However, it never hurts to review some guitar basics: Fretting: The small metal strips on the guitar neck. If you're right-handed, then the first fret is the one farthest to the left. To play a fret, you push the string down just to the left of fret (right-handed). So, to play the 3rd fret you'd play just to the left of the third metal strip, so your finger is between the second and third frets. Strings: The six strings are ordered, starting from the thinnest string on the bottom, as eBGDAE. The thinnest string is the 1st string, the thickest string (on top) is the sixth string.
