The Sound of Feelings: Affective Timbre and Music as a Model of Affect, Feeling, and Emotion

Three problems remain open once emotion is understood as an interpretation of feeling. Hedonic tone cannot account for the full qualitative character of a feeling; emotion theory still blurs bodily mechanism, conscious feeling, and emotion; and an emotional category must hold very different instances together without a shared essence. I argue that music answers all three, not as decoration but as a working model of the levels of emotional life.

Musical timbre distinguishes instruments that play the same note at the same loudness, and I introduce affective timbre as the qualitative character through which a feeling presents itself beyond how pleasant or unpleasant it is. Four thought experiments about instruments, a deaf engineer, a dancer, and music-recognition software then separate the levels that research on emotion tends to merge, and I assign each phenomenon its own level. Finally, musical genre models the emotional category: varied instances held together by constraint rather than essence, with emotional grammar deciding which variation a category admits.

The resulting correspondence runs from instrument to physiological affect, sound to feeling, timbre to affective timbre, composition to an emotion, and genre to an emotional category.
