A Ukulele is a instrument with 4 strings. The word ukulele means bouncing fleas in Hawaiian. The ukulele was named and made in Hawaii, but was inspired by Portugal's four-stringed machete. People used to bring guitars out to sea to sing on a ship. Then, people from Portugal traded ukuleles in Hawaii. That is when the ukulele got its name.

In the year 1886, the ukulele became the official instrument of the Islands when King Kalakaua took it up and featured it for the first time with hula dancers.
