Ukulele Tuner FAQ
Quick answers for using this ukulele tuner effectively.
What is standard tuning for a ukulele?
Standard ukulele tuning is G4, C4, E4, A4, moving from the 4th string to the 1st string. This is the common reentrant setup.
What is Low-G tuning?
Low-G tuning changes the 4th string from G4 to G3. That gives the ukulele a lower range and a different feel for melody and accompaniment.
How do I use this online ukulele tuner?
Click a string button to hear that pitch. Match your ukulele string to the reference sound. Click the same button again to stop, or use the Stop button to silence everything.
What does Tuning Shift do?
Tuning Shift moves all the reference pitches together. That helps if you want to tune down a half step, down a whole step, up a half step, or up a whole step.
What is Play All Strings for?
Play All Strings gives you the full sequence of string pitches one after another. It is useful for checking the whole ukulele quickly before you start playing.
