This talk will address the question of what it is for music to possess emotional and other psychological content ; and what it is not. It will discuss the relations of the approach suggested to other recent theories (Robinson, Schlenker). More generally, it will address the relations between constitutive philosophical theories on the one hand and both scientific and historical issues on the other. It will consider the relation of a constitutive account to autism and musical understanding ; to the visual perception by the audience of musical performers ; and to the structure of underlying representations involved in music perception in the mind-brain. Time permitting, it will also discuss the contributions constitutive philosophical accounts can make to the characterization of musical styles.
