There’s no getting around it, the way a ukulele is strung is absolutely ridiculous. But that’s what makes it such incredible instrument.
Almost all stringed instruments go from lowest string (thickest) to highest string (thinnest). Not the ukulele. The ukulele strings sizes go like this from nearest your head to nearest the ground:
G string: Second thinnest.
C string: Fattest.
E string: Second Fattest.
A string: Thinnest.
Anyone who has experience with string instruments will find this baffling. I certainly did. When I first bought a cheap ukulele and, being a guitarist, was completely ignorant, I changed the order of the strings. Now I’m much wiser and know that this is the only way to have your strings.
