One of the most common tunings for ukulele (uke) is G C E A.
I remember this by remembering the sentence George Clooney Eats Ants.
The fourth string (the string nearest to your nose when the uke is in the playing position is tuned to G.
The third string is tuned to C.
The second string is tuned to E.
And the first string is tuned to A.
