The first thing you need to learn for basic guitar playing is the standard tuning. If your guitar isn’t tuned, you cannot learn how to play it. In case you are a beginner, tuning your guitar can be a problem.
Fortunately, you can take your instrument to a nearby guitar store and get professional help. In case you want to take matters into your own hands, you might have to spend a lot of time. Buy yourself a guitar tuner which gets connected to your guitar’s neck. Now simply ring each and every string, one at a time, and go in this order: E A D G B E. This should be the standard tuning of your guitar which should be displayed on the tuner from the thickest to the thinnest string. An easy way to remember E A D G B E is through this sentence: Eddy Ate Dynamite Good Bye Eddy.
After you are done with learning the standard tuning, it is time for you to learn all the notes. Notations can be tricky, but they always are in alphabetical order.
You must remember that all notes have a sharp note attached to them, except E and B notes. So basically, while you are learning how to play different notes, the first string should sound something like this (staring from the first fret): E, F, F#, G, G#, A, A#, B, C, D, E and so on. Similarly, all other strings can also be played according to the alphabetical order. Notice that as soon as the notations reached the G# note, there was no H note available; therefore, it went back to the A note. From there on, the alphabetical order started from A and then so on. Similarly, once you are taking notes on the A string, everything will already be in order.
