How To Tune Your Ukulele
So you just bought a new ukulele and excited to play some tune. Or you already have an old ukulele hiding you’re your bed or in storeroom for quite some time. It always advisable to get the strings in tune before you started playing. And I always advised my students to check and tune the instrument before every practice, it will also help train your ears to know the sound of a correct tone. Here are some ways to tune your ukulele.
The open strings of the ukulele are as follows.

Using Electronic Tuner
One of the easiest and most accurate ways is to use an electronic Tuner. This is also the method I prefer the most. There are many brand and model of tuner available online and also in your local music store. Most aren’t that expensive and will make your life easier. Just make sure to get one that is made to tune ukulele or a chromatic tuner which can be used to tune different notes. To use the tuner is pretty easy, your just clip the tuner on the headstock and pluck the strings. It will show the note you are playing and you use the tuning pegs to get to the desired note.
Refer to the tuner manual or user guide on how to operate the model of tuner you have.

Using “Relative” Tuning Method
For this method, you tune the strings relative to each other, i.e. with reference to the other string. This method isn’t that accurate as if the first string you use as reference is out of tune, all of them will be out. It fine if you are playing on your own but will cause issues if you are playing with other people or along with songs.
This may take some practice to train your ear.
For the below example, I am using the 1st string (A) as the first reference string.
Tip: You can try to train yourself to remember how the first string (A) sound like so at least it won’t get too far out after you had tuned your ukulele.
Here are the steps.
1) Tuning 2nd stings (E) with reference to the 1st string (A).
You use the 1st string (A) as a reference. Then place your finger on the 5th fret of the 2nd string (E). Now you pluck the 1st string (A) and 2nd string (which is now an A note), they should sound the same. You can adjust the 2nd string with the tuning pegs until they sound the same.

2) Tuning 3rd stings (C), with reference to the 2nd string (E).
Next place your finger on 4th fret of the 3rd string (C). Now you pluck the 2nd string (E) and 3rd string (which now is an E-note), they should sound the same. You can adjust the 3nd string with the tuning pegs until they sound the same.

Tuning 4th stings (G).
4a) Most of the ukulele comes with a High G string. For this case you use the 1st string (A) as reference.
Place your finger on 2nd fret of 4th string. Now you pluck the 1st string (A) and 4th string (which now is an A-note), they should sound the same. You can adjust the 4th string with the tuning pegs until they sound the same.

4b) If you had replaced the 4th string to a Low G string, you use the 2nd string (E) as reference.
Place your finger on 5th fret of 4th string. Now you pluck the 2nd string (E) and 4th strings (which now is an E-note), they should sound the same. You can adjust the 4th string with the tuning pegs until they sound the same.

Using Piano Tuning Method
You can use a piano to tune your ukulele. Refer to diagram below to match the notes of the piano with that of your ukulele.

Still can’t get it in tune?
Your ukulele may not been setup properly, this may be resolved by tightening the screws of the machine heads a little. Or the strings aren’t put on correctly. A new set of strings also need some time to settle down as you may notice it will get out of tune again pretty fast. And remember to always check is your ukulele in tune before every practice session.
Enjoy playing and have fun.
