Mood is a phenomenon whose study is inherently interdisciplinary. While it has remained resistant to theorisation, it nonetheless has a substantial influence on art, politics and society. Since its practical omnipresence in every-day life renders it one of the most significant aspects of affect studies, it has garnered an increasing amount of critical attention in a number of disciplines across the humanities, sciences and social sciences in the past two decades. Mood: Aesthetics, Psychology, Philosophy provides a comprehensive theoretical and empirical exploration of the phenomenon of mood from an interdisciplinary angle. Building on cutting-edge research in this emerging field and bringing together established and new voices, it bridges the existing disciplinary gap in the study of mood and further consolidates this phenomenon as a crucial concept in disciplinary and interdisciplinary study. By combining perspectives and concepts from the literary studies, philosophy, musicology, the social sciences, artistic practice and psychology, the volume does the complexity and richness of mood-related phenomena justice and benefits from the latent connections and synergies in different disciplinary approaches to the study of mood.
