The ukulele (/ˌjuːkəˈleɪli/ YOO-kə-LAY-lee; Hawaiian: [ʔukulele] 'OO-koo-leh-leh); also called a uke (informally), is a member of the lute (ancient guitar) family of instruments. The ukulele is of Portuguese origin and was popularized in Hawaii. The tone and volume of the instrument vary with size and construction. Ukuleles commonly come in four sizes: soprano, concert, tenor, and baritone.
Ukuleles generally have four nylon strings tuned to GCEA. They have 16–22 frets depending on the size.
