How to Tune Guitar in Standard Tuning

Standard guitar tuning from the thickest string to the thinnest string is E, A, D, G, B, E. Many beginners say it from low to high because that matches how the strings sit when you hold the guitar.

The two E strings are in different octaves. The low E is thick and deep. The high E is thin and bright. If the tuner shows the right letter but the string sounds wildly wrong, check the octave and string position.

Start with the low E string and work across the guitar. Mute the other strings with your picking hand so the tuner hears only the string you are adjusting.

Pluck near the middle of the string with a moderate attack. Very hard picking can make the note start sharp, while very soft picking can produce an unstable signal.

If a string is sharp, lower it past the target and tune back up. This habit keeps tension consistent and reduces the chance that the string slips flat after the first chord.

After all six strings are tuned, check them again. Changing one string changes neck tension slightly, especially on floating bridge guitars.

After the tuner says each string is correct, play a few open chords you know well. If one chord sounds off, retune carefully and make sure you are not pressing too hard with the fretting hand.

Old strings, poor intonation, or a sticky nut can make a guitar sound out even when the open strings are tuned. If the problem repeats, the guitar may need a setup.
