“Canorous” is based on the Latin “canorus,” meaning “melodious,” and “canere,” meaning “sing.” The melodious quality of a canorous human voice is created by the anatomy of the larynx. While many parts of the mouth and throat contribute to producing sound, the larynx, also known as the voicebox, determines tone and timbre of vocal sound. A vocal coach will teach a singer to relax their larynx in order to produce a canorous tone, as opposed to a high or reedy sound.
