There is nothing in the world of guitar playing more important than guitar tuning. You can be a great guitar player but if you play for people out of tune they will leave. Listeners can take a mistake or two but do not play out of tune.
If you use a standard tuning method you will be in tune with the rest of the world. A 440 hertz A note is the same all over the world.
The important thing is you will be able to train your ears better if you are constantly in tune. An A note will always be 440 on the money not below or above. You will learn to recognize the notes easier.
Sometimes it not possible to be perfectly in tune like playing along with an out of tune piano or older keyboard of some type but try as much as possible to stay in tune.

If you are going to play with another guitar player getting in tune with each other is even more important. If one of the guitars has a string out of tune it will stand out much more than if you were playing alone.
This is because you will probably both be playing the same notes at the same time at some point during a song. This can also cause very long useless arguments about which of you is out of tune. Have you been there?
This is the official name for being in tune with the rest of the world. The important thing about being in tune all the time is more about training your ears than being in tune.
This is very important. Training your ears is essential. Universities that offer music as a major have ear training the entire length of their courses. If you just randomly tune to play you will have a harder time training your ears to hear pitches correctly.
Check out the page below to tune up and learn about the different tuners. Some come with metronomes too which is a useful tool.
What you need to tune is one note that you know is accurate, a tuning fork will do but not as accurate because of temperature and humidity changes, but it doesn't need batteries.
A guitar tuner will most likely be the best choice especially if you are just starting to play. A song that you know with a long note in it will do in a pinch.
Breaking a few strings in the beginning is normal, especially the first and second string on a light set of strings. Experience is the solution, remember what you did wrong and try not to do it again. This train of thought will help your guitar playing as well as tuning.
What makes guitar tuning a pain is that the guitar neck layout is not perfect, it varies in accuracy depending on where you play the notes. This is the nature of the guitar.
You may find your guitar in tune in the first position but not in the upper positions. This is usually intonation. The positioning of the bridge and the fret lay out.
This will not prevent you from getting started playing. Again experience will help you. Don't get hung up because you can't get your guitar in tune perfectly. Harmonics can also play tricks with your ears.
Here is a link where I buy guitar accessories, they're quick delivery and have good prices.
I have a metronome with a tuner in it. It only gives an A note which I like better than trying to tune 6 different strings to 6 different notes.
Personally I like to tune from one note that is true like from a tuning fork, guitar tuner or a song with a good long note that you know. To me this is much easier than trying to tune six different strings to six different notes. Especially if you are just starting out.
Tuning this way will help prevent you tuning from an out of tune string. Every string is tuned from the fifth string.
My metronome has an A note to tune with so this is why I use it but the A 440 hertz seems to the common tone for tuning many instruments not just guitar.
This way of tuning has been around for as long as I can remember.
Try both ways and see which way you like better. There is no right or wrong way to tune your guitar no matter what you may read. They are basically opinions.
The bottom line is are you in tune? That is all that matters
Experiment and try other ways of tuning once you know the guitar neck.
P.S. This is not the only tuning for guitar. This is the standard way of tuning that the majority of people use. There are many other tunings used by various artists. E, D, dropped D, and G are just a few I will show you later on another page.
