The short answer: To tune a ukulele, you need to adjust the four strings to the notes G, C, E, and A (from the top string to the bottom). Use a clip-on tuner, a tuning app, or tune by ear using a reference pitch. Turn the tuning pegs to raise or lower the pitch until the tuner shows the correct note. With practice, it takes less than a minute.
Standard ukulele tuning is G-C-E-A, which is the most common tuning for soprano, concert, and tenor ukuleles. The strings are numbered from the string closest to your chin when you hold the uke: the top string (G) is the fourth string, then C (third), E (second), and A (first). This is known as ‘reentrant tuning’ because the G string is not the lowest pitch; it is actually tuned above the C string. This gives the ukulele its bright, cheerful sound.
Before you start, make sure your ukulele is in good condition. If it’s brand new, it may take a while to stay in tune as the strings stretch. You can speed up stretching by gently pulling each string upward after tuning, but be careful not to break them.
A clip-on tuner is the easiest and most accurate way to tune, especially for beginners. Clip it to the headstock of your ukulele, making sure it has good contact. Turn it on, and it will detect the vibrations of the strings.
Pluck the top string (G) and look at the tuner’s display. It will show the note name and whether you are flat (too low) or sharp (too high). Turn the corresponding tuning peg to adjust: tightening (clockwise) raises the pitch, loosening lowers it. Aim for the display to show ‘G’ and the needle or light to be centered. Repeat for C, E, and A strings.
Clip-on tuners are affordable and work well even in noisy environments. If you don’t have one, you can use a smartphone app like GuitarTuna or Fender Tune, which use the built-in microphone. Just place your phone near the uke and follow the same process.
Tuning by ear is a valuable skill, but it takes practice. You can use a reference pitch from a piano, another tuned ukulele, or an online tuning video. Play the reference note and compare it to your string. Adjust the peg until they sound identical.
Another trick is the ‘relative tuning’ method: assume your C string is in tune (or tune it to a reference), then fret the C string at the 4th fret to get the E note, tune your E string open to that pitch. Fret the E string at the 3rd fret to get G, tune your G string open to that. Finally, fret the C string at the 2nd fret to get the A note, tune your A string to that. This method ensures the uke is in tune with itself, but not necessarily to absolute pitch.
For absolute pitch, use a tuning fork or pitch pipe. Hit the tuning fork and hold it near your ear, then tune the A string to it, then use relative tuning for the rest. This is a traditional method but is less common now.
One common mistake is turning the wrong peg. The tuning pegs are located on the headstock and correspond to the strings they control: the top-left peg goes to the G string (the string closest to you when holding), the top-right to the C string, bottom-right to the E, and bottom-left to the A. Double-check which peg you are turning.
Another mistake is tuning too quickly and overshooting the pitch. Turn the peg slowly and pluck repeatedly. If you are using an app, make sure there is no background noise.
If your ukulele won’t stay in tune, it might be new strings needing time to settle, or the tuning pegs may be loose. Tighten the screws on the pegs slightly, but not too much. Also, check that the strings are properly wound around the pegs and have a good break angle at the nut.
To keep your ukulele in tune, store it in a case or away from extreme temperatures and humidity. When you pick it up, it may be slightly out of tune due to changes. Always check tuning before practicing, as playing out of tune can hinder your ear training.
If you are just starting, consider investing in a quality ukulele that holds tuning better. A good instrument makes a difference. Check out our buying guide for recommendations: Best Ukuleles.
Tune every time you play. Even if it was in tune yesterday, temperature and humidity changes can affect it. With practice, tuning becomes quick and automatic.
Low G tuning is an alternative where the G string is an octave lower. The notes are still G-C-E-A, but the string set is different. If you have a low G string, the tuning process is the same, but the G will be lower in pitch. You can use a tuner to set it accurately.
Yes, you can tune by ear using a piano, another instrument, or by relative tuning. However, for beginners, using a tuner is highly recommended to develop pitch recognition. The more you tune, the better you become at hearing pitches.
