Resonance
Quick Definition
The amplification and enrichment of vocal sound through the acoustic properties of the vocal tract cavities above the larynx.
Factual Definition
The acoustic phenomenon where sound waves produced by the vocal folds are filtered and amplified by the resonating cavities (pharynx, oral cavity, nasal cavity). Resonance is shaped by adjusting the size and shape of these cavities, which determines which frequencies (formants) are emphasized.
Full Explanation
Resonance is fundamental to vocal sound production. The raw sound created by the vibrating vocal folds (the ‘source’) is relatively weak and buzzy. It’s the resonating cavities of the vocal tract that transform this source sound into the rich, projected tone we recognize as a singing voice.
The vocal tract acts as an acoustic filter, emphasizing certain frequency bands called formants. By adjusting the position of the tongue, jaw, lips, soft palate, and larynx, singers can shape their formants to achieve different tonal qualities, increase projection, or modify vowels for better acoustic efficiency at high pitches.
Understanding resonance empowers singers to achieve more volume without pushing, find their optimal ‘ring’ or ‘ping,’ and navigate the acoustic challenges of different parts of their range.
