I have heard people get some pretty good music out of the little "standard" ukulele, but I can't say I could work up a great deal of enthusiasm for it. But the "Guitalele," the size of a tenor uke and with six strings (tuned like a guitar with a capo on the fifth fret), is capable of some pretty interesting stuff.

Actually, it could be considered a one-quarter-size guitar.
