There has been an explosion of interest in sonic seasoning in recent years, building on the emerging literature concerning the existence of consensual crossmodal correspondences between sonic and gustatory properties. However, to date, a musical match for the metallic taste has not been reported (nor looked for). Here, based on the authors' intuition, we tested, and by so doing demonstrate, that the sound of the theremin, associated with old sci-fi movies is strongly associated with a metallic taste.
Spence et al. (Wed,) studied this question.
