This chapter explores the notion of attunement in correlation with Stimmung, mood, and atmosphere through the understanding of phenomenology. It starts with Edmund Husserl’s lectures on inner time consciousness through music and Martin Heidegger’s philosophy of Stimmung and its early reception in the field of music. Philosopher Joseph Kockelmans, musicologist Karol Berger, and English philosopher Andrew Bowie understood the concept of Stimmung, also comprehended as mood, within the field of music. Thus, researchers used a whole series of concepts closely related to the idea of attunement in the analysis of contemporary culture and art. The chapter then notes the emergence of atmosphere, referencing how new phenomenology and its associated aesthetics comprehended that emotions are atmospheres poured out spatially.
