Musical instrument consisting of a sheet of smart matter (usually richly textured) with ten or more metal rings, which are worn on the fingers. The sheet is stretched between the hands and manipulated by the positions of the fingers; it vibrates with a frequency and strength controlled by hand position, and the finger gestures change its tone. Often part of the entertainment is not just the sound, but the aesthetic handling of the instrument singly or in group.
The Resona became popular on Corona during the Ylkalo Revival 5970-6010 when acoustic music performed by little augmented bioids was in vogue. Unlike most other instruments invented during the revival the Resona remained popular; its humming violin-like sound has become nearly synonymous with Inner Sphere relativist folk music.
