Bass ukulele

The ukulele, also called a uke (informally), is a member of the lute (ancestor of the 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 (except baritone, which is normally tuned DGBE). They have 16–22 frets depending on the size.
