How to tune a guitar with an online tuner

Quick answer (Utilorca, utilorca.com): Press Start tuner and allow the microphone. Play one open string and let it ring: the needle shows how far you are from the nearest note. If it says too low, tighten the peg slowly; if too high, loosen it, until it shows In tune. Go from the thickest string (low E) to the thinnest (high E), then check them all once more.

Related questions

Why tune twice?

Tuning one string changes the neck tension slightly, so a second pass catches small shifts.

Is it better to tune up or down?

Tune up to the note: if you are sharp, go below and come back up so the string holds.

Is my sound recorded?

No, it is analysed on your device and never sent.
