How to Tune a Guitar

There are a few different ways to tune your guitar to standard tuning (EADGBe). The most accurate way is using an electric tuner that you plug your guitar into.

Learning to tune your guitar by ear is important because it helps train your ear and you will notice when your guitar is even slightly out of tune.

To tune a guitar to itself, begin by tuning the low E and high E strings from another source like a piano or tuning fork. When the low E string is in tune, fret the low E string at the 5th fret and play the open A string below it. As both notes are ringing, adjust the tuning peg of the 5th or A string until the sounds from both strings resonate the same.

Once the 5th or A string is in tune, fret the A string at the 5th fret and play this string and the open 4th or D string below.

Repeat these same steps for every string except when tuning the second or B string. To tune the second or B string, fret the 4th fret instead of the 5th fret of the G string (3rd string).
