01 — Method

Tune it step by step

Open the free tuner, choose Acoustic guitar and begin with E2, the thickest string.

Pluck the string clearly and let it ring. Avoid touching the other strings while the tuner is listening.

If the pitch is flat, tighten the string a little. If it is sharp, loosen it slightly.

For better stability, approach the target pitch from below instead of overshooting it.

Move through all six strings, then check them once again because changing one string can slightly affect the others.

02 — Tips

A few tips that make tuning easier

New acoustic strings stretch a lot during the first hours. Retune several times.
Use a medium, clean pluck. Hitting the string too hard can make the first pitch reading unstable.
If a chord still sounds wrong after tuning, check string condition and intonation.

03 — FAQ

How often should I tune an acoustic guitar?

Ideally before every playing session, and again whenever the instrument has been moved, exposed to temperature changes or fitted with new strings.

Which direction should I turn the tuning peg?

The safe rule is to watch the pitch rather than rely on a direction: turn very slightly, pluck again and confirm whether the note moved up or down.
