The term 'Guitars' Kin' refers to two stringed instruments that are related to the guitar: ukes (4 letters) and lutes (5 letters). Ukes are small, four-stringed instruments that originated in Hawaii and are now popular around the world. Lutes are larger, pear-shaped instruments that have been around since the Middle Ages and are still used in some traditional music styles. Both ukes and lutes are played with a pick or fingers and are similar to guitars in their construction and tuning.
