How to tune a 7 string guitar online

Tap Turn on to start the tuner and allow microphone access when prompted. Pluck one open string clearly and let it ring until the tuner settles on a note. You will see the detected note and whether the pitch is flat or sharp. Turn the tuning peg in small steps, then pluck again to confirm the change. Tune one string at a time until the reading centers on the target note. After all seven strings are set, recheck them once more from the highest string back down.

Standard 7 string tuning and target notes

Most 7 string guitars use standard tuning with an added low string: B E A D G B E from low to high. The note list on the page shows your targets so you can move string by string without guessing. Start with the low B and tune up through the set, keeping adjustments small to avoid overshooting. When you reach the higher strings, aim for a steady reading and make fine corrections slowly. If you use an alternate tuning, begin by matching the closest standard notes, then adjust each string to your preferred pitches.

Tips for clearer low-end detection

The low B string produces strong overtones, so tune in a quiet room and let the note sustain longer. Pluck with a moderate attack and try picking closer to the middle of the string for a clearer fundamental. If the tuner jumps between notes, mute the other strings and pluck again with a lighter touch. Once the low string is stable, the rest of the set usually becomes easier to tune. After a few minutes of playing, check the low B again, since changes in neck tension can affect it more than the higher strings.
