Tune your ukulele with your phone or computer microphone. Open the page in your browser, allow microphone access, and play one string at a time. The tuner identifies the note it picks up and tells you whether to increase or decrease the tension. The result depends on your device's microphone, surrounding noise, and the way you play.

The most common tuning for soprano and concert ukuleles is GCEA: G, C, E, and A. In the traditional setup, the fourth string uses high G. With equal temperament and A4 at 440 Hz, the strings correspond to G4, 392.00 Hz; C4, 261.63 Hz; E4, 329.63 Hz; and A4, 440.00 Hz. The fourth string, therefore, is not the lowest. This arrangement helps create the short, bright attack heard in pop, rock, folk, country, and worship accompaniment.

The tenor may use the same tuning. The baritone usually follows DGBE, close to the four lowest strings of a guitar. There is also the setup with low G, generally identified as low G. It replaces G4 at 392.00 Hz with G3 at 196.00 Hz and changes the shape of melodies and fingerpicking patterns.

Use the table below to check the expected note, but do not treat frequency as a guarantee independent of the device. The tuner listens to the sound reaching the microphone. For that reason, playing technique, phone distance, and room noise change the reading. The following steps show how to reduce these errors today.

Notes and frequencies for ukulele tuning

In reentrant GCEA tuning, the string order from fourth to first is G4, C4, E4, and A4. The fourth string is in a high register. This is the setup most often found on soprano and concert ukuleles.

StringNoteReference frequencyNote
4thG4392.00 HzHigh G in reentrant tuning
3rdC4261.63 HzLowest note in the GCEA setup
2ndE4329.63 HzBetween C4 and A4
1stA4440.00 HzReference pitch for tuning A

These values use A4 at 440 Hz. The device may show small variations because of pickup and noise. To tune, look for the correct letter and watch whether the reading remains stable for 2 or 3 seconds. Do not adjust based only on the first number that appears.

If your ukulele uses low G, the fourth string changes to G3 at 196.00 Hz. Do not try to reach this note with a string set made for high G. Check the string-set packaging and the manufacturer's recommendation before turning the tuning peg.

How to tune a ukulele by microphone in under a minute

Put the ukulele in a stable position. Rest the body on your leg and keep the sound hole unobstructed. Open the online ukulele tuner in your browser and allow microphone access. If the browser asks again, choose the option to allow access while the page is open.

Play only the fourth string. Use your fingernail or fingertip with medium force. Let the note ring for 2 or 3 seconds. Compare the displayed letter with G, C, E, or A, depending on the string. Turn the tuning peg in movements of approximately 1/8 turn. Play again after each adjustment.

In GCEA tuning, follow this sequence: fourth string G4, third C4, second E4, and first A4. The fourth string is the highest in the traditional set, even though it occupies the position many people associate with the lowest string. Do not copy guitar string order, since a guitar has six strings and a different relationship between the notes.

If you pass the desired note, lower the tension until you are below it, then raise it slowly. Finish the adjustment by increasing the tension. This procedure helps the string settle at its contact points and reduces the rebound caused by slack in the tuning peg.

After tuning all four strings, play two or three chords. A simple progression such as I–V–vi–IV reveals changes that do not appear on an open string. To compare the ukulele with another instrument, open the guitar tuner, but keep the ukulele's note references. To test a groove at 60 to 72 BPM, use the online metronome.

Check again after playing for 1 minute. New strings may drop soon after the first chords. If that happens, repeat the adjustment instead of tightening the string all at once.

Why ukuleles go out of tune, and what you can prevent

String tension changes when you replace the set, transport the instrument, or expose the ukulele to changes in temperature and humidity. Nylon strings usually settle during the first few hours. A practical procedure is to tune, play for 5 minutes, tune again, and repeat the check before rehearsal.

Your left hand also changes the note. When forming a chord, you may push the string sideways or press harder than necessary. This raises the pitch, especially at the first few frets. Press only until the note sounds clean. If the chord goes sharp when you press, place your finger just behind the fret and try using less pressure.

The nut, saddle, and tuning pegs create friction points. When the string catches at one of them, tension becomes uneven between your hand and the bridge. You adjust the tuning peg, release the string, and notice that it returns to a different note. If this always happens on the same string, do not treat the problem as simple detuning.

Heat and cold also affect the instrument. Do not leave the ukulele in a trunk, near a window with direct sunlight, or next to a stove or shower. During a 30-minute trip, carry the instrument in a case and wait a few minutes before tuning, especially if it has gone from a hot car to an air-conditioned room.

After tuning, check a sequence in the chord generator. Play, for example, four chords in cycles of 4 beats. A string that seems correct by itself may reveal instability when it takes part in a progression used in country, folk, or worship music.

Ukulele tunings and when to switch between them

GCEA tuning suits most soprano and concert ukuleles. It works for pop, rock, folk, country, and worship accompaniment. The soprano has a shorter scale and usually concentrates more notes in the first few frets. The concert offers slightly more room for the left hand while keeping the same standard tuning.

The tenor accepts GCEA and also appears in low-G configurations. Its larger body often favors projection and fingerpicking. If you play a melody with many leaps between the fourth and first strings, test the chosen setup before changing the string set. The same fingering can produce another octave when low G replaces high G.

The baritone is different. Its most common tuning is DGBE, from the fourth to the first string, with the same notes as the four lowest guitar strings. A chord shape learned on soprano should not automatically be transferred to baritone. Check the model, scale, and string-set recommendation before making the change.

Use low G when you need a more prominent low line, want to reduce melodic leaps, or intend to highlight fingerpicking. Use high G when you prefer the typical reentrant attack of pop and folk accompaniment. The choice should match the string set and the instrument's setup.

To return to the main tuning, change one string at a time and review all four at the end. Then check a sequence in the chord progressions material. In a common I–V–vi–IV progression used in worship arrangements, an open string in a different register changes the color of the accompaniment even when the chord names remain the same.

Strings, tension, and the difference a new set makes

A new set changes the feel of the instrument and tuning stability. A freshly installed string is still stretching. Tension also distributes itself among the tuning peg, nut, and saddle. For that reason, the ukulele may seem in tune for 20 seconds and then drop after a sequence of eight or ten chords.

After installing the string, tune to the correct note and perform gentle stretches along the neck. Pull the string only a few millimeters away from the fingerboard at three or four points, without using sudden force. Play again and tune. Repeat until the drop decreases. Do not do this on a string that already shows damage, a kink, or wear.

Lower-tension strings make chords and bends easier but respond more to finger pressure. Higher-tension strings feel firmer but require more left-hand control. The result depends on the ukulele's size, scale, setup, and the attack of your right hand. The set's tension rating must be compatible with the instrument.

Traditional nylon usually produces a rounder attack. Fluorocarbon tends to respond faster and may have more noticeable brightness. Changing material does not correct a high nut, poorly seated saddle, or loose tuning peg. If the high-G fourth string feels slack, compare the tension listed on the packaging before buying another set.

Write the replacement date on a piece of paper inside the case. After 2 or 3 weeks of regular use, compare brightness, response, and stability. If one string loses response before the others, investigate dirt and friction points before replacing it out of habit.

When the tuner will not stabilize: noise, pickup, and old strings

If the letters jump between two notes, reduce sound sources. Close tabs that play audio, turn off the television, move the phone away from speakers, and choose a room without a running fan. Conversations several feet from the device can already interfere with the reading of a low-intensity string.

Move the device closer to the ukulele's sound hole, but do not cover the microphone with your hand. A distance of 10 to 20 centimeters often makes pickup easier without making the sound excessively loud. Play one string at a time and mute the others with your palm or the fingers of the hand that is not adjusting.

Avoid a full strum during the reading. The tuner may pick up a neighboring string or a stronger harmonic. Play near the center of the string with medium intensity. If the note does not appear, slightly increase the attack and wait 2 seconds. Striking too hard can raise the note at first and confuse the reading.

Check microphone permission in the browser. If you blocked access, open the site settings, allow it again, and reload the page. On a computer, test the internal microphone and another available microphone. The tuner depends on the device's pickup and does not replace listening to the note.

An old string may lose brightness, respond slowly, and waver at a specific point. Compare the suspect string with another one, always at the same volume and distance from the device. Look for dirt, wear, or a kink near the nut. To practice listening without depending only on the display, also read the guide on how to tune by ear. The exercise works for a four-string instrument.

How to check tuning with chords and rhythm

An open string is only the first check. Form an open chord and play each string slowly. Then strum for 4 beats. If the note changes when you press the chord, reduce left-hand pressure and place your finger just behind the fret.

Use a tempo of 60 BPM to test a fingerpicking pattern. Play one note per beat for 8 beats and listen to whether the pitch remains stable. Then increase to 72 BPM and perform the same check. This range is enough to expose strings that drop after several attacks without turning the test into a fast performance.

For a pop or rock groove, start at 72 BPM and play only the rhythmic pattern, without singing the lyrics. In a country accompaniment, use four chords in cycles of 4 beats and watch whether the first string remains stable in chords with open A. In a folk or worship introduction, play a slow fingerpicking pattern and compare tuning between the low and high notes.

If the open string is correct but chords sound high at the first fret, the problem may be the action, nut, or finger pressure. The tuner cannot identify by itself whether the cause is the setup. Write down which string and fret show the deviation. This information helps a luthier locate the friction point.

How to keep your ukulele in tune between rehearsals

Before storing it, tune all four strings and play with the intensity expected in rehearsal. Check again after 5 minutes. If the same string drops in both measurements, inspect the tuning peg, nut, and saddle. Simply tightening the string can hide the problem for a few minutes.

Store the instrument in a case, away from windows, kitchens, bathroom doors, and heat sources. Do not leave the ukulele in a trunk. The case reduces impacts and direct exposure but does not control every change in temperature and humidity. When you arrive somewhere very different, wait a few minutes before adjusting.

Clean the strings with a soft, dry cloth. Do not use alcohol, detergent, cooking oil, or household cleaning products. Remove excess sweat after playing. Check for rough spots at the nut, loose tuning pegs, and uneven wear near the saddle.

Build this routine: tune when you arrive, play for 5 minutes, check again, and only then begin rehearsal. In pop, rock, and country repertoire, repeated right-hand attacks quickly reveal an unstable string. To access other study resources, open the Cantivy tools. If you are working on a samba groove, keep the tempo steady so you can hear tuning within the rhythm.

Perguntas frequentes

What is the most common ukulele tuning?

The most common tuning is GCEA, used mainly on soprano, concert, and tenor ukuleles. From the fourth to the first string, it corresponds to G4, C4, E4, and A4. With A4 at 440 Hz, the reference frequencies are 392.00 Hz, 261.63 Hz, 329.63 Hz, and 440.00 Hz. In the traditional setup, the fourth string uses high G, not low G. This arrangement appears in pop, rock, country, and folk accompaniment.

Can I tune a ukulele with my phone's microphone?

Yes. Open the tuner in your browser, allow microphone access, and play one string at a time. Test it in a quiet place, move the phone near the instrument's sound hole without covering the microphone, and let each note ring for 2 or 3 seconds. The reading depends on the device's pickup, surrounding noise, and playing force. If it fluctuates, mute the other strings and reduce the room volume.

Why is the ukulele's fourth string higher?

In traditional GCEA tuning, the fourth string uses G4 at approximately 392.00 Hz. It does not follow the low-to-high order typical of a guitar. This setup is called reentrant tuning and places a high note at the beginning of the set. The result contributes to the bright, jumping attack heard in pop, rock, and folk strumming. Some string sets use G3 at approximately 196.00 Hz, but this change alters the instrument's response.

How long does a new ukulele take to stabilize?

There is no single timeframe for every instrument. During the first few hours, new strings may drop several times as they settle. Tune, play for 5 minutes, and check again. Perform gentle stretches at three or four points on the string without pulling hard. If a string remains unstable after several days of regular use, inspect the tuning peg, nut, saddle, and possible kinks in the string.

What should I do when the tuner does not recognize a string?

Reduce noise, move the device near the ukulele's sound hole, and play the isolated string. Mute the others with your hand and wait 2 seconds before adjusting. Avoid striking hard, because strong harmonics can interfere with the initial reading. Also check microphone permission in the browser. If only one string fails, see whether it is old, dirty, kinked, or catching at the nut.

Is tuning a ukulele the same as tuning a guitar?

The microphone procedure is similar, but the notes are different. A ukulele has four strings and commonly uses GCEA. A guitar has six strings and uses EADGBE in standard tuning. Do not copy guitar string order. On the ukulele, check G, C, E, and A from the fourth to the first string. If you open the <a href="/ferramentas/afinador/">guitar tuner</a>, use it only as a process reference and confirm the ukulele notes.

When should I use low G on a ukulele?

Use low G when you want a stronger low register, fingerpicking with greater contrast, or melodies with fewer leaps between the fourth and first strings. The fourth string changes from G4 at approximately 392.00 Hz to G3 at approximately 196.00 Hz. Make the change with a set designed for low G. A regular high-G string may have unsuitable tension. After the change, review all four strings and check the setup.

How can I prevent my ukulele from going out of tune during rehearsal?

Tune before starting, play for 5 minutes, and check again. Press chords with moderate force and avoid pushing the strings sideways. Transport the instrument in a case and do not leave it in a car. If one string always drops, investigate the tuning peg, nut, saddle, and wear. In a rehearsal at 60 to 72 BPM, repeated attacks quickly reveal an unstable string.

Do old strings make the tuner unstable?

They can. Old strings lose response and brightness, collect dirt, and may wear at their contact points. The tuner may pick up a note that wavers or takes time to appear. Compare its behavior with another string at the same distance from the device and with similar playing force. If the problem continues, replace the set and check again after 5 minutes and after 1 hour of use.

What are the frequencies for GCEA ukulele tuning?

With A4 at 440 Hz, GCEA tuning uses G4 at 392.00 Hz on the fourth string, C4 at 261.63 Hz on the third, E4 at 329.63 Hz on the second, and A4 at 440.00 Hz on the first. These values are references for the tuning system. The actual reading depends on the phone or computer microphone, noise, and attack stability.

Does a tenor use the same tuning as a soprano ukulele?

In most cases, yes. Soprano, concert, and tenor ukuleles may use GCEA. The tenor also accepts variations such as low G, provided the string set is compatible. Body and scale size change the feel and projection but do not automatically change the tuning notes. Check the manufacturer's recommendation before replacing the set.
