The image above is a map of the fretbaord. Heres how it works. In music there is only 7 notes A,B,C,D,E,F,G. Inbetween these notes there are sharpes and flats, sharpes and flats have the same value the only diffrence is when going up you refer to the notes as sharpe and when going down you refer to them as flats (for the sake of learning).

The notes always follow this order. A Asharpe/bflat B C Csharpe/Dflat D Dsharpe/Eflat E F Fsharpe/Gflat G Gshapre/Aflat then it starts over again.

Ok this is where it starts to make sense. Each string has a name these are the names from thickest to thinest E,A,D,G,B,E (there are two E strings the thin E and the thick E. Notes on these strings are the same) all you have to do to firgure out the notes on each string is follow the pattern. For example the E stirngs. You would start on E which is open then fret 1 would be F fret 3 would be G fret 5 would be A etc.

this works for every string and once you get to the 12th fret the pattern starts over again. (Note there are no sharpes and flats between B and c and E and F)

At first all this might be to much to take in but learning and memorizeing the notes on your fret board will be important later on. The best way to do this is to sit down and play the notes. Memorize the E strings pefrectly then the A string etc. Take it one string at a time and dont move on until you have memorized the notes on the previous string. There are other ways to learn notes like learning the notes on each fret but i found my way alot better. It might take a while but belive me you will be glad you did it. Try doing this for ten miniutes when you start practice each day it will also warm up your fingers.
