That's correct, Bob, the baritone is tuned DGBE, while the standard tuning for the soprano, concert, and tenor ukes is GCEA. At the risk of sounding like a spokesman for the Department of Redundancy Department...the instrument is an ukulele, it means "jumping flea" in Hawaiian, and the Hawaiian pronunciation is "oo-koo-lay-lay", not "you-ka-lay-lee"--though people in Hawaii also call it a "uke". The two most likely explanations for the name are: (1) The English sailor, Edward Purvis, who popularized the instrument in the Hawaiian Royal Court was nicknamed "Ukulele" because of his abundant energy and his being altitudinally challenged (which I personally feel is a mark of greatness). (2) The name refers to the nimble fingers of an accomplished player.

Here's a fascinating site that explains chord theory and construction on the ukulele; if you go to the main page of Ukuleles by Kawika, you'll find a wealth of additional information by a Hawaiian instrument builder.

I love the old "hapa haole" and Tin Pan Alley tunes, but I'm hoping to learn more traditional Hawaiian music as well. The "chord melody" style that's very popular here is a bit beyond me. Also, I'd recommend the series of books by Jim Beloff (Jumpin'Jim's Ukulele Tips and Tunes is the "primer") as a good introduction and song resource for the beginning player.
