(1) A continuing or echoing of sound. (2) A richness and variety in the depth and quality of sound.
Example:
Audiences for both Star Wars and CNN are drawn to the resonance in the voices of James Earl Jones.
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 masters Stradivari and Guarneri, for example, possess a quality of resonance that modern violinmakers have not been able to duplicate.
