 It is an important question whether a physical theory of sensible features should just provide a physical candidate for each determinate sensible feature, or whether the physical relationships among those physical candidates should capture the structural relations among sensible qualities (and, if so, which structural relations it should capture). This is an example of how considering in detail the nature and the experience of sensible qualities other than color promises insights into traditional debates concerning the sensible qualities. Pautz (2014) offers an empirically-grounded argument concerning a variety of sensible qualities, including audible qualities, that advances such discussion.
