Abstract: A guitar has a body and a neck extending from the body. The body has a central core and two panels sandwiching the core means between them. The side edges of the panels are curved toward each other and secured, so that both panels are rounded convex outwardly. At one end of the lenticular cavity thus defined the body is closed by suitable panel means. The other end is left open, and preferably has two upwardly and outwardly sloping openings.
