The singing voice can be considered a wind instrument and has three components: voicing, resonance and articulation. The oral and nasal cavities have very important functions when you sing. They are used as acoustic resonators for your voice along with the larynx (See Blog “Unlocking The Key To Your Voice” 11/4/20) and pharynx. They both act as resonators (See Blog “The Sound Transmission of Your Voice” 11/9/20) that amplify in various degrees of intensity. Think of them as chambers or caverns; have you ever been in a cave and yelled hearing an echo resonating through the cave. This is what the oral and nasal cavities do, but in a smaller capacity. The voiced sounds are amplified and modified by the vocal tract resonators.

The nasal cavities act as a resonator for your voice. These cavities can add higher frequencies and expand the brightness and vitality of your voice.

The oral cavity, which includes the lips, teeth and tongue serve as articulators (See Blog “The Tools We Use To Sing” 12/12/20). The oral cavity also acts as a resonator to amplify and intensifies your voice.

Listen to Audrey Diaz sing “Riptide,” you can hear the resonance and acoustic amplification in her singing.
