While you play, an arrow on the peg shows which way to turn it. Machine heads vary, so if the note moves the wrong way, turn the other way.

Open E tuningE B E G♯ B E

Open E tunes the strings to an E major chord: E B E G♯ B E. It's bright and punchy, and a classic slide guitar tuning. It raises three strings, so tune up gently.

Tuning your guitar to Open E

Automatically with the microphone, or by ear: tap any note on the headstock to hear a real recorded reference.
  1. 1

    Allow microphone access when your browser asks. The audio is analysed on your device and never uploaded.

  2. 2

    Pluck one string at a time and let it ring. The tuner detects which string you're playing.

  3. 3

    If the needle is left of centre the string is flat, so tighten it. If it's right of centre the string is sharp, so loosen it.

  4. 4

    Turn the peg slowly until the note turns green and the needle sits in the middle. Then move on to the next string.

  5. 5

    Go round once more: tuning one string slightly changes the tension on the others.

Questions & troubleshooting

What are the notes of Open E tuning?
Open E tuning on guitar is E B E G♯ B E, from the lowest string to the highest.
How do I tune to Open E from standard tuning?
Starting from standard (E A D G B E): string 5 up a whole step, string 4 up a whole step, string 3 up a half step. Every other string stays the same. Use the tuner above to check each string.
Is Open E tuning bad for my guitar?
No. Changing tuning is completely safe. Just tune gradually, and when raising pitch go slowly so you don't over-tighten a string. After a big change, the neck can take a day to settle, so check your tuning again.
