Why does the guitar belong to string family?

The guitar belongs to the string family because it produces sound by the vibration of strings. When a string is plucked, it vibrates and produces sound waves that are amplified by the guitar's body. The guitar's strings are made of different materials, such as nylon, steel, or bronze, and they are tensioned to different pitches. The tension of the strings, along with the length and thickness of the strings, determines the pitch of the sound that is produced.

The guitar is a member of the string family of instruments, which also includes instruments such as the violin, viola, cello, and double bass. These instruments all produce sound by the vibration of strings, and they are all played in a similar manner. The guitar is one of the most popular instruments in the world, and it is used in a wide variety of genres of music.
