The purpose of this blog post is to simply explain in a practical way what resonance is to the voice user and how it can be used to increase the ease and efficiency of singing and speaking.
Titze and Verdolini – Abbot refers to resonance as “reinforcements of natural oscillations” (Vocology The Science and Practice of Voice Habilitation 29).
In physics resonance is a phenomenon in which a vibrating system or external force drives another system to oscillate with greater amplitude at specific frequencies — Wikipedia
Resonance is vibrations that create tone through and within your mouth, throat, and nasal passages — Pamela Phillips, Singing for Dummies
In simplest terms, the voice is constructed of a power source (the lungs), a source (vocal folds also known as vocal cords) and a resonating tube(airways or vocal tract.) Furthermore, every voice vibrates and creates a pitch which is determined largely by the size of the vocal folds (please see blog post “But Size Does Matter.”) That resonating tube has certain characteristics, which influence the sound created; however, by understanding the ABCDs of resonance we can use the information to change to conform to social requirements, or to improve it to ensure greater efficiency, ease, and a reduction of work.
