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.
More specifically, the term "lute" can refer to an instrument from the family of European lutes. The term also refers generally to any string instrument having the strings running in a plane parallel to the sound table (in the Hornbostel–Sachs system).
