How to tune a 4 string banjo online

Press "Tap to tune" to start the tuner and allow microphone access when prompted. Pluck one open string and let it ring so the tuner can lock onto the pitch. The display shows the note and whether you are flat or sharp. Turn the tuning peg in small steps, then pluck again to recheck. Tune each string one at a time until the note centers. Finish with a quick second pass to confirm everything stayed in tune.

Standard 4 string banjo tuning and note targets

A common 4-string banjo is most commonly tuned in fifths: C G D A. Use the note list on the page as your target and tune slowly, since small turns can shift pitch quickly. Many players tune the longer strings first, then set the short fifth string last so it matches cleanly. If you use another tuning, start from the closest standard notes and adjust each string to your intended targets.

Tips for banjo accuracy and steady tuning

Banjos ring with strong overtones, so tune in a quiet room and play one string at a time. Mute nearby strings and use a consistent, moderate attack. Small peg turns make a noticeable difference—adjust slowly and recheck.
