Tune a 7-string guitar to standard B-E-A-D-G-B-E or Drop A with a matching seven-peg layout and low-register microphone detection.
Standard 7-string guitar tuning adds a low B1 below the familiar E-A-D-G-B-E six-string layout. Drop A lowers that seventh string from B1 to A1 while the remaining strings stay standard.
The target setup on this page is B1 - E2 - A2 - D3 - G3 - B3 - E4.
Pitch analysis runs continuously in the browser and displays the nearest target, frequency, and cents difference.
The tuner shows whether the current note needs to move up, move down, or is within the in-tune range.
Select a visible target to hear a clean reference pitch when you want to compare the instrument by ear.
Microphone samples are analyzed locally and are not uploaded as an audio recording.
Tune in a quiet room and play only one clear note or open string at a time.
Start with B1 - E2 - A2 - D3 - G3 - B3 - E4. Available alternatives include Standard BEADGBE and Drop A AEADGBE.
Allow microphone access, keep the instrument close enough for a clean signal, and avoid other sustained sounds.
Play one open string and let it sustain while the tuner selects or follows its target.
Move gradually toward the center, then repeat every target because changing one string can slightly affect the others.
Use the dedicated preset when the target notes and physical string order matter more than a general chromatic reading.
Tune the low B first, then continue through the same six open-string targets used by a standard guitar.
Lower only the seventh string to A1 for one-finger low power chords while keeping the upper six strings standard.
Mute the other strings and let the low B or A settle so the detector does not lock onto an overtone.
Lock the tuner to the low target when automatic mode moves to a neighboring octave or pitch class.
Both use the same pitch detector, but they organize targets differently.
| 7-String Guitar Tuner preset | Chromatic mode | |
|---|---|---|
| Targets | B1 - E2 - A2 - D3 - G3 - B3 - E4 | All twelve semitones |
| Visual layout | Instrument-specific pegs and strings | Detected note and cents |
| Best for | 7-String Guitar Tuner | Custom tunings and other pitched instruments |
| Tuning choice | Standard BEADGBE and Drop A AEADGBE | No instrument tuning required |
A dedicated preset is easier when you want the correct string order. Chromatic mode is more flexible when you already know the target note.
Yes. It runs in a supported browser without requiring an account or installing a tuning app.
The default targets are B1 - E2 - A2 - D3 - G3 - B3 - E4.
Yes. Allow microphone permission, keep the device near the instrument, and play in a quiet place for a more stable reading.
One semitone contains 100 cents. A negative reading is flat, a positive reading is sharp, and a value close to zero is in tune.
Other strings, room noise, overtones, and a hard attack can compete with the fundamental. Mute unused strings and read the note after it settles.
No. Live microphone analysis stays in the browser and the tuner does not create or upload an audio recording.
