What are the notes of standard guitar tuning?

From the thickest (6th) string to the thinnest (1st): E A D G B E. A common way to remember it is 'Eddie Ate Dynamite, Good Bye Eddie'.

Is my microphone audio recorded?

No. The sound is analysed in your browser to detect pitch and is never recorded or uploaded.

Why does the tuner jump around?

Pluck one string at a time, let it ring, and reduce background noise. Hold the phone or laptop close to the guitar's sound hole.

How often should I tune my guitar?

Every time you play. Temperature, humidity and new strings all make guitars drift out of tune.

How to tune your guitar with this tuner

Press Start tuner and allow microphone access when your browser asks.

Pluck one string and let it ring. The big letter shows the note the tuner hears.

If the needle is left of centre, the string is flat: tighten it slightly. Right of centre means sharp: loosen it.

When the needle stays in the green and the display says "In tune", move to the next string.

Tip: always tune up to the note. If you're sharp, go a little below and come back up. The string holds its pitch better that way.

Other popular tunings

Drop D (D A D G B E): lower the 6th string a whole step to D. You get heavier power chords and one-finger chords on the bottom three strings.

Half-step down (E♭ A♭ D♭ G♭ B♭ E♭): every string a semitone lower. Many rock and blues players use it for a warmer sound and easier string bends.

Tuning troubleshooting

The note keeps jumping? Mute the other strings with your hand, reduce background noise and hold the mic close to the guitar.

It reads the wrong octave? Pluck more gently. Very hard plucks produce strong overtones.

New strings won't stay in tune? That's normal. New strings stretch for the first day or two, so retune often.

Once you're in tune, practise in time with our Online Metronome, or try the Online Piano.

FAQ

Does this work for ukulele, violin or singing?

The note display is chromatic, so it shows any note it hears. You can tune other instruments or check your singing pitch, but the string buttons are set up for guitar.

Is my audio recorded?

No. Sound is analysed in your browser in real time and never recorded or sent anywhere.
