The ukulele is a Hawaiian musical instrument developed from the Portuguese guitar. It has a fretted fingerboard and four strings that are plucked or strummed. A similar instrument is the banjolele, which has a banjo body. The ukulele became popular in the US through a 1915 exposition held in San Francisco, at which the Hawaiian Pavilion featured a guitar and ukulele ensemble. Vaudeville performers took it up, and its popularity spread. “Ukulele” is Hawaiian for what? Discuss
