The chapter consists of an encyclopedia that lists, describes, and assesses metaphors that often are used to describe sound quality. Each entry explains the embodied cognitive patterns that connect sound descriptors with the listening experience. Each entry also discusses related terms, and each term is examined in relation to its metaphorical use and the discourses underlying sound and music communities. The encyclopedia includes 15 pairs of opposing terms: balance/unbalance, big/small, clean/dirty, clear/blurred, dark/bright, fat/thin, full/hollow, heavy/light, open/closed, organic/synthetic, rough/smooth, soft/hard, tight/loose, warm/cold, and wet/dry. The terms are distilled from a 50-million-word collection of texts concerning sound culled by the author from music reviews, hi-fi magazines, and the sound engineering literature.
