How to tune a ukulele if you don’t have anything like a ukulele tuner, piano or tuning fork? Nothing is easier! Use the online tuner to tune your ukulele using the microphone on your computer or smartphone.
Launch the tuner and allow access to the microphone by pressing the "Allow" button.
Starting with the first, play an open string and check the accuracy of the setting by the table (by note or frequency).
Adjust all stringlines 1 to 4 alternately, after which it is recommended to check the setting of all stringlines in reverse order.
