Tuning your ukulele or guitar is an important thing to learn how to do.  Even though it is probably harder to tune one than to play one, once you get the hang of it, it’s not so hard.
In the video below, I demonstrate how to use a tuner app to tune my ukulele.  You’d use the same method to tune a guitar, bass, or another string instrument.

In the video, I used an app called GuitarTuna and you can use it one a computer to tune a guitar, but to tune a ukulele using a computer, try Uke Buddy.
