Ukulele was first invented in Portugal and prevailed in Hawaii. It looks more like a smaller version of the guitar. It has four strings, two fewer than the guitar.
Ukulele looks like a guitar, but their temperament is very different. The guitar is like a big brother in the family who is responsible, there will be dull, low-pitched, and occasionally enthusiasm. Ukulele is more like a little girl at home. She is carefree and relaxed by the care of her brothers and sisters. No wonder ukulele is known as a musical instrument that makes people smile.
