The world's smallest musical instrument is a toothpick guitar - Apparently.
The toothpick guitar, also known as the "Dentalina", was created in 1991 by a German instrument maker, Roland Heinrich. It has a single string and is played by plucking the toothpick with a pair of tweezers. The instrument is just 6.5 cm (2.5 in) long and weighs 0.5 grams. Despite its tiny size, it produces a surprisingly rich and clear sound, making it a unique addition to the world of music.
