The study of 'music and #emotion' 

seeks to understand the psychological relationship between human affect and music. It is a branch of music psychology with numerous areas of study, including the nature of emotional reactions to music, how characteristics of the listener may determine which emotions are felt, and which components of a musical composition or performance may elicit certain reactions. The field draws upon, and has significant implications for, such areas as philosophy, musicology, music therapy, music theory and aesthetics, as well as the acts of musical composition and performance. weki
