Practice fretting the strings. The frets are the metal strips that run perpendicular to the strings that mark each note. To play a note, press your finger down between the metal strips, not on them. To say that you're playing the third fret means that you place your finger on the string in the gap between the second and third fret. If you hear buzzing, move your finger away from the lowest fret and closer to the higher fret. Hold the string down firmly so that it only vibrates between your finger and your strumming hand, with the tip of your finger doing the pressing.
After you have selected a style and a teacher, you may want to keep some extra questions in mind for your first guitar lesson. An in person lesson can be very valuable, if you show up, and if you do the work that the instructor gives you for when you are not meeting. One of the greatest methods of improving is to consistently play. Play multiple times a week, get those practice repetitions in.
Learn how to read tabs. Tabs will have six lines that represent your strings, along with numbers that designate where you should be placing your fingers. The numbers represent the fret in which you need to hold the string down. A 1 means the first fret, a 2 means the second fret, and so on. Numbers in a progression mean that you hold down the first individual fret and pick the note, then move to the next one, and so on in succession. Numbers on the same vertical line are meant to be played together simultaneously as a chord.
