What is a fretted stringed instrument?

A fretted stringed instrument is a musical instrument that has strings stretched over a fingerboard. The fingerboard is divided into sections by frets, which are thin strips of metal or other material that are set into the fingerboard. When a string is pressed against a fret, the string's length is shortened, which changes the pitch of the note that is produced.

Fretted stringed instruments include guitars, banjos, mandolins, ukuleles, and many others. These instruments are all played in a similar way, with the player using their fingers to press the strings against the frets to produce different notes.

The fretting system on a fretted stringed instrument allows for a great deal of control over the pitch of the notes that are produced. This makes fretted stringed instruments very versatile instruments, and they can be used to play a wide variety of music.
