Resonance Uses Beyond Sound

Many of the finest musical instruments possess a high degree of resonance which, by producing additional vibrations and echoes of the original sound, enriches and amplifies it. Violins made by the Italian masters Stradivari and Guarneri possess a quality of resonance that later violinmakers have never precisely duplicated. And you may have noticed how a particular note will start something in a room buzzing, as one of the touching surfaces begins to resonate with the note. Because of that, resonance and resonate—along with the adjective resonant—aren't always used to describe sound. For example, you may say that a novel resonates strongly with you because the author seems to be describing your own experiences and feelings.
