According to The Guinness Book of World Records, the ukulele is the easiest instrument to play. If you're just lookin' to pick up a few chords so you can serenade your sweetheart, the uke is for you. If you plan to make the study of the uke your life's work, then you too can benefit from a lesson in tuning.
Experimentation can produce effects ranging from the sublime to the psychedelic.
If, however, you plan to learn songs from sheet music and want to play together with other people, it helps to know the conventional tunings of the ukulele. There are basically two dominant schools of which you should be aware. We refer to them as the Old School and the New School. Practically speaking, there's not much difference between them, but the Old School is a lot cooler.
