When was ukulele invented?

1879, Portuguese professional craftsmen and musical instrument producers ManuelNunes, JoaoFernandes and AugustineDias came to the Hawaiian Islands. As immigrants, they invented and developed the guzheng in their hometown while working in sugarcane fields. Hawaiians are not only surprised by the beautiful timbre of this piano, but also by the rapid movement of the player's fingers on the fingerboard. [2]

From then on, Hawaiians called this piano You Creary, which means "jumping flea".
