Learn to Tune your guitar
Tuning your guitar is one of the most important things you can do for yourself while you learning to play. We will go over several methods of tuning and ways to train your ears while you are learning to tune. Once when your ear is trained, you won’t have to worry about whether your digital tuner is with you or not.
As a beginner, I suggest that you go get yourself a digital tuner. It is the easiest way to tune guitar for the beginers.
When you are tuning your guitar with the digital tuner, you should watch carefully on lights on tuner, when you pluck the string than the light should become green if the string is tuned, and it should be written the letter of the string (for example E) if it is not well tuned than the light will be red. You can tune all strings that way.
After while you can start to tune with tuner only first string E and the rest of strings you can tune by ear. It is like this 2nd string B press on 5th fret and pluck you should have exactly the same sound like you have on 1st string E empty, than 3rd string G press on 4th fret and pluck, the sound must be the same like the 2nd string empty, than follow the procedure with 4th, 5th and 6th string always on 5th fret.
An important reminder: Be sure that you tune as often as you can that is the way to train your ears. Don’t just tune at the beginning of a session. Tune several times per session. This will help you hear intonality (when notes aren’t in tune) and get your ears trained.
