About UkuleleThe ukulele ( YOO-kə-LAY-lee; from Hawaiian: ʻukulele [ˈʔukuˈlɛlɛ], approximately OO-koo-LEH-leh) is a member of the lute family of instruments. It generally employs four nylon strings.The ukulele originated in the 19th century as a Hawaiian adaptation of the Portuguese machete (cavaquinho), a small guitar-like instrument, which was introduced to Hawaii by Portuguese immigrants, mainly from Madeira and the Azores. It gained great popularity elsewhere in the United States during the early 20th century and from there spread internationally. The tone and volume of the instrument vary with size and construction. Ukuleles commonly come in four sizes: soprano, concert, tenor, and baritone.
