Lute

A lute (/ljuːt/[1] or /luːt/) is any plucked string instrument with a neck and a deep round back enclosing a hollow cavity, usually with a sound hole or opening in the body. It may be either fretted or unfretted.

The term also refers generally to any string instrument having the strings running in a plane parallel to the sound table

The strings are attached to pegs or posts at the end of the neck, which have some type of turning mechanism to enable the player to tighten the tension on the string or loosen the tension before playing (which respectively raise or lower the pitch of a string), so that each string is tuned to a specific pitch. The lute is plucked or strummed with one hand while the other hand "frets" the strings on the neck's fingerboard. By pressing the strings on different places of the fingerboard, the player can shorten or lengthen the part of the string that is vibrating, thus producing higher or lower pitches
