The ukulele is a member of the lute family of instruments. It generally employs four nylon strings.

The tone and volume of the instrument vary with size and construction. Ukuleles commonly come in four sizes: soprano, concert, tenor, and baritone.

Ukulele varieties include hybrid instruments such as the guitalele, banjo ukulele, harp ukulele, lap steel ukulele and the ukelin. It is very common to find ukuleles mixed with other stringed instruments because of the amount of strings and the easy playing ability.
