One comment on the text at 1:00. The ukulele was not developed in Portugal, but rather by Portuguese immigrants living in Hawaii. It's a product of syncretism, or two cultures combining together. It adapts several pre-existing Portuguese instruments, notably the cavaquinho and rajão, into the Hawaiian musical tradition. Manuel Nunes claimed to be it's inventor, and while this was never verified, he did own the very first ukulele store.
