Jangle refers to a sound that is sharp, metallic, and often discordant, typically produced by objects like keys or small bells clanging together. This term is commonly used in music to describe a bright, ringing quality, especially in genres like rock or indie pop, where guitars may create a jangly sound. In a broader context, "jangle" can also describe a feeling of unease or tension, often associated with anxiety. This emotional jangle can arise from stressful situations or environments, leading to a sense of discomfort or agitation in individuals.
