Perfect lines? Check. Musical medley? Check! A Musical Ruler gives you the perfect creative outlet while working ceaselessly at your desk. Unlike other musical instruments, this plastic ruler requires no teacher, no tutor, no genius whatsoever! A thorough guidebook holds your hand through scaling, finger placement, and ruler movement. Just place at the end of a desk or hard surface, and let the music ruler rock harder than a V-shaped flame-covered guitar! The Musical Ruler still functions as a regular ruler with its straight edges, but hey, who needs a basic ruler when you can create auditory delight as well?
