Ukuleles are usually very small and light four-stringed instruments, but Lawrence Stump from the USA has created a tuneable and playable ukulele that is a giant 3.99 metres (13 ft 1.08 in) long.
His supersized musical instrument has entered the Guinness World Records 2017 Edition as the world's Largest ukulele.
The body of the instrument is constructed of birch plywood, and the neck and head are of pine, as are all four tuning pegs.
The ukulele has the correct fret spacing required to produce notes separated by a semitone, as is the case on a normal-sized uke. In fact, it is an exact, to-scale replica of a commercially available Soprano ukulele - but 7.5 times larger.
Lawrence first got the idea to build the world’s largest ukulele after helping his son construct a regular-sized one for a science project at school.
Playing the largest ukulele 
The record was verified during an event in a music store in Lansing, Michigan, where Lawrence demonstrated his giant ukulele could really play, as required by the Guinness World Records rules for this title.
“Holding a Guinness World Records title is a distinct honour, knowing my instrument could meet the requirements I had to try,” said Lawrence.
Holding up the largest ukulele 
Previously, the largest ukulele was 2.27 m (7.45 ft) long, 0.85 m (2.8 ft) wide and 0.25 m (0.83 ft) deep and was created by Xuri Musical Instruments Co. Ltd. (China) in Zhangzhou, Fujian, China, on in 2014.
Lawrence's creation is featured in the Guinness World Records 2017 Edition alongside of loads of incredible record-breaking inventions.
