A guitar is a popular musical instrument that has six strings, although some variations have more. It is played by strumming or plucking the strings with fingers or a pick. Guitars can be made from different materials, such as wood or plastic, and come in various shapes and sizes. They are used in many music genres, including rock, jazz, and classical. There are two main types of guitars: acoustic and electric. An acoustic guitar produces sound naturally through its hollow body, while an electric guitar requires an amplifier to enhance its sound. Many famous musicians, like Jimi Hendrix and Taylor Swift, have made the guitar a central part of their music.
