This is a simple way to check your tuning and to tune your ukulele. With this method you have to get at least one of your strings in tune (preferably the low G string), because from that string you will tune the rest of your strings using that as a reference. If you don't have access to a tuning fork, keyboard, or other tuning device, then that's fine. You can get one string as close as you can by ear and then tune the rest of the ukulele to it. The ukulele will be in tune with it's self and will sound just fine, even if every string is a little sharp or flat. Just make sure if your playing with someone that your in tune with them.

Open Strings - Down below I will talk about playing Open Strings. To play an Open String means to play a string without fretting anything. So that's why it's called Open.

Use the picture as a reference, Assuming now that your 4th String(G string) is in tune....

• Play the 5th fret on the 4th String(G String) and the open 3rd String(C String). Both these notes are C, but the sound the 4th string produces is one octave higher than the open 3rd string. You can still use it to tune. Just make sure you tune the 3rd string to a C that is an octave lower than the note on the 5th fret 4th string. If you try and tune it exactly to this note you will break your string, so make sure you tune it an octave lower.
• Now that the 3rd String(C String) is in tune we can now tune the 2nd String(E String) to it. Fret the 4th fret on the 3rd string(C string) and play that string and the open 2nd String(E String), and then turn the pegs on the 2nd String(E String) till they match.
• Same process again, fret the 5th fret on the 2nd String(E String), and tune the open 1st String(A String) to the fretted 2nd String(E String).

Your ukulele should now be in tune.

Congratulations on tuning your ukulele!

Note: Most ukuleles are constructed economically, meaning that the fretting isn’t always exactly perfect. That means you want to use the lower frets to tune. Check out another article called Tune the ukulele to itself using non-adjacent strings. This article teaches you a way to tune your ukulele fretting notes lower on the fretboard so the imperfections in the placement of the frets do not affect the reference note as much.
