Abstract: A case for a stringed musical instrument has its enclosure or body in the form of a right triangular prism to present spaced apart parallel panels with right triangular perimeters and a peripheral wall extending between such perimeters of the panels and having right angularly related portions with contiguous ends, and preferably of different lengths, and a diagonal portion extending between the other ends, and the carrying handle extends from the peripheral wall at a location between the ends of the diagonal portion which is selected so that with the longer of the right angularly related portions of the peripheral wall extending substantially vertical, the handle will be substantially in vertical alignment with the center of gravity of the case with the instrument therein.
