The Ukulele is a four-string plucked instrument that originated in Hawaii. It looks similar to a guitar, but is smaller in size and has a bright and crisp sound. The four strings of the ukulele are usually made of nylon or natural catgut and can be played with fingers or picks. The ukulele is often used for accompaniment and solos, and is an important instrument in Hawaiian music. It is easy to learn and play, so it is very popular, becoming a common accompaniment instrument in pop music, folk music and country music.
