The ukulele from hawaii is a member of the lute family of instruments. It generally employs four nylon or gut strings or four courses of strings. Some strings may be paired in courses, giving the instrument a total of six or eight strings.
The ukulele originated in the 19th century as a Hawaiian adaptation of the Portugese Machette a small guitar-like instrument, which was introduced to Hawaii by Portugese Imigrants 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.
