FAQ from Ukulele Tuner
What tuning modes does the online ukulele tuner support?
Ukulele Tuner supports four common ukulele tuning modes: gCEA standard tuning, aDF#B soprano tuning, DGBE tuning, and fA#DG baritone tuning. Most soprano, concert, and tenor ukuleles can start with gCEA.
How do I tune my ukulele online using the microphone?
Click start tuning and allow microphone access, then pluck one string at a time. The tuning meter will show whether the pitch is too high or too low. Slowly turn the tuning peg until the needle approaches the center and stays steady.
How do I tune my ukulele without microphone access?
You can use the reference tone mode: click each string button or press the Q, W, E, R shortcuts to play the target notes, then match the pitch by ear. In noisy environments or when the microphone is unavailable, reference tones are usually more reliable.
Is this ukulele tuner free?
Completely free. No registration, no installation, and no paywall—use the ukulele tuner, reference tones, and multiple tuning modes directly in your desktop or mobile browser.
How can I avoid breaking strings while tuning?
Turn the tuning pegs slowly and re-pluck the string to confirm after each small adjustment. If a string suddenly feels very tight or the pitch goes above the target, stop immediately and loosen it slightly to avoid breaking ukulele strings.
Why is the tuning meter reading unstable or jumping?
This may be caused by background noise, resonance from other strings, or unclear plucking. It's best to pluck only one string at a time in a quiet environment, lightly mute the other strings with your fingers, and stay close to the microphone for more stable readings.
