The Cat’s Face has two tuned arrays of metal prongs, one short and one long. The prongs are plucked in three different ways to bring out different modes of vibration, and each mode has its distinctive tone quality. In the short array, the prongs have wire-loop rattles to add a glittery edge to the tone. Originally the soundboard of the Cat’s Face was mounted on a styrofoam sound box. That’s now gone, and it’s equipped with a pickup instead.
