How to Tune a Guitar — Standard EADGBE Tuning and Online Tuner

Even a perfectly fretted chord sounds off if the guitar is out of tune — and practicing on an out-of-tune guitar can actually train your ear the wrong way. The good news: tuning takes about a minute. This guide covers standard tuning order, how to use a free online tuner, tuning without one, and drop D.

🎯 Bottom line: Standard guitar tuning, from the thickest string, is E · A · D · G · B · E. With a free online tuner that uses your microphone, pluck each string from low E and tune until the needle centers. No app install or sign-up needed.

Memory trick: "Eddie Ate Dynamite, Good Bye Eddie." Just remember the 6th and 1st strings are both E and you won't get lost.

How to Tune with a Free Online Tuner (4 Steps)

1

Open the tuner and allow the microphone

Open the online tuner and allow microphone access. The quieter the room, the more accurate it is. Keep the guitar close to the mic (laptop or phone).

2

Start with the low E string

Pluck the thickest low E string once. If the note shown is below pitch (flat), tighten the tuning peg; if above (sharp), loosen it.

3

Go in order: E A D G B E

Tune each string in order from low E to high E: E, A, D, G, B, E. The string is done once the needle sits dead center.

4

Do a second pass

Tightening one string slightly shifts neck tension and can pull others out of tune. Check all six strings once more for a stable result. New strings stretch, so check them often.

Tuning Without a Tuner (5th-Fret Method)

Once one reference string (usually low E) is in tune, you can tune the rest using the 5th-fret method. Fretting the 6th string at the 5th fret should match the open 5th string, and so on: 5th string, 5th fret = open 4th, 4th string, 5th fret = open 3rd, 3rd string, 4th fret (only this one) = open 2nd, 2nd string, 5th fret = open 1st. Adjust until each matching pair sounds identical. If your reference string is off, everything else will be too — so tune that first string with a real tuner.

FAQ

What order are guitar strings tuned in?
From the thickest (6th) string to the thinnest (1st): E A D G B E. Low E is the lowest note on the guitar; high E is two octaves above it.
Can I tune a guitar without a tuner?
Yes, with the 5th-fret method — match each string's 5th fret to the next open string. One reference string still needs a tuner or piano first for accuracy.
How do I use an online guitar tuner?
Allow the microphone, then pluck strings from low E. Tighten if flat, loosen if sharp. Centered needle means done — no app install needed.
Should I tune up to pitch or down to pitch?
Finish by tightening up into pitch from slightly flat. Loosening down from sharp can make the string slip out of tune again quickly.
What is drop D tuning?
Standard tuning with just the low E dropped a whole step to D (D A D G B E). Common in rock/metal since it lets you play power chords with one finger.
