Open E Tuning on 6-string guitar
Open E tuning is E2 B2 E3 G#3 B3 E4, written EBEG#BE. Raise the 5th, 4th and 3rd strings: A2 to B2, D3 to E3, G3 to G#3. The 6th, 2nd and 1st stay where they are.
| String | Note | Frequency (Hz) | MIDI |
|---|---|---|---|
| 6th (lowest) | E2 | 82.41 | 40 |
| 5th | B2 | 123.47 | 47 |
| 4th | E3 | 164.81 | 52 |
| 3rd | G#3 | 207.65 | 56 |
| 2nd | B3 | 246.94 | 59 |
| 1st (highest) | E4 | 329.63 | 64 |
Every frequency is computed from the MIDI number, not typed in. Each one links to its own reference page.

Why guitarists use Open E tuning
It is open D shifted up a whole step, so it has the same shapes with brighter, tighter strings. The catch is that three strings go up rather than down, which increases tension on the neck, so many players use open D with a capo at the second fret instead to get the same pitches at lower tension.
Where you will hear it: blues, slide guitar, rock. That list is deliberately limited to genres and playing traditions. Attributing a tuning to specific songs or players is the kind of claim that needs a source, and this page does not make claims it cannot back up.
Open E compared with standard EADGBE tuning
This is the table that tells you how far to turn each peg, in semitones and in hertz. A negative semitone value means the string goes down.
| String | Standard | Standard (Hz) | Open E | Open E (Hz) | Change |
|---|---|---|---|---|---|
| 6th (lowest) | E2 | 82.41 | E2 | 82.41 | unchanged |
| 5th | A2 | 110.00 | B2 | 123.47 | +2 semitones (+13.47 Hz) |
| 4th | D3 | 146.83 | E3 | 164.81 | +2 semitones (+17.98 Hz) |
| 3rd | G3 | 196.00 | G#3 | 207.65 | +1 semitone (+11.65 Hz) |
| 2nd | B3 | 246.94 | B3 | 246.94 | unchanged |
| 1st (highest) | E4 | 329.63 | E4 | 329.63 | unchanged |
Notice that equal semitone steps are not equal hertz steps: the same whole step is worth about 9 Hz down at the bottom string and far more at the top. That is why tuners report cents, which are proportional, rather than hertz.
How to tune to Open E, string by string
- Play the 6th (lowest) open and adjust until the tuner reads E2 at 82.41 Hz. Aim to land inside five cents.
- Play the 5th open and adjust until the tuner reads B2 at 123.47 Hz. Aim to land inside five cents.
- Play the 4th open and adjust until the tuner reads E3 at 164.81 Hz. Aim to land inside five cents.
- Play the 3rd open and adjust until the tuner reads G#3 at 207.65 Hz. Aim to land inside five cents.
- Play the 2nd open and adjust until the tuner reads B3 at 246.94 Hz. Aim to land inside five cents.
- Play the 1st (highest) open and adjust until the tuner reads E4 at 329.63 Hz. Aim to land inside five cents.
Retune in two passes. Changing the tension on one string changes the pull on the neck, so the strings you set first will have drifted slightly by the time you finish the last one. That effect is larger the further the tuning sits from standard, so a tuning that moves four or more strings almost always needs a third pass.

What notes is Open E tuning on a 6-string guitar?
Open E is E2, B2, E3, G#3, B3, E4, written EBEG#BE. Raise the 5th, 4th and 3rd strings: A2 to B2, D3 to E3, G3 to G#3. The 6th, 2nd and 1st stay where they are.
What are the frequencies of Open E tuning?
E2 is 82.41 Hz, B2 is 123.47 Hz, E3 is 164.81 Hz, G#3 is 207.65 Hz, B3 is 246.94 Hz, E4 is 329.63 Hz, all in twelve tone equal temperament with A4 at 440 Hz.
How many strings change compared to standard tuning?
3 of 6. the 5th goes from A2 to B2 (up 2 semitones), the 4th goes from D3 to E3 (up 2 semitones), the 3rd goes from G3 to G#3 (up 1 semitone).
What is the lowest note in Open E tuning?
E2 at 82.41 Hz, MIDI note 40. Low notes take longer for a pitch detector to lock onto, so play the string firmly and let it ring before trusting the cents reading.
