Theorists of music and emotion have come to recognise a wide range of aesthetic and non‐aesthetic situations in which music serves as a vehicle, or a trigger, or a catalyst, for emotional experience. In this essay I focus on aesthetically warranted emotions (AWEs) as real, measurable emotions that are directly motivated by stylistically competent interaction with composed expressive trajectories (CETs). Through a close interpretation of the exposition of the second movement of Mozart's Piano Sonata in F, K. 533, I explore five central issues: (1) the role of marked musical gestures and stylistically unmarked alternatives in reconstructing and interpreting CETs; (2) the affordance of prior emotional experience for an individual's complete cognitive understanding of CETs; (3) whether or not one need actually experience AWEs in order to cognitively understand and appreciate CETs; (4) whether emotional engagement need always be congruent with, or isomorphically constrained by, CETs in order to qualify as AWEs; and (5) the status of AWEs, and our cognition of them, as multi‐levelled and integrative, synthetic and emergent, and varying in intensity.
