The term 'Guitar's Kin' refers to three different stringed instruments: ukes (4 letters), uke (3 letters) and LUTE (4 letters). Ukes are small, four-stringed instruments that originated in Hawaii and are often used in Hawaiian music. Uke is a shortened version of the word ukulele. A LUTE is a plucked string instrument with a long neck and a deep round back, and is one of the oldest instruments still in use today. All three instruments are related to the guitar, as they all have strings and are plucked or strummed.
