Vocal warm-up: Resonators

Use of the "M" with closed mouth to activate resonators.

Once the "source" (lungs and strings) is warmed up, we must activate the "amplifier" (the resonators).

The human body has bony cavities in the face and skull that act as a resonance box.

To awaken them, we use the exercise of the "M" held with the mouth closed (boca chiusa).

A continuous nasal sound ("mmmm") is emitted, seeking to feel a physical tingling or vibration in the lips, nose and cheekbones.

This tactile sensation confirms that we are placing the voice "forward," in the "mask," rather than trapped in the throat.

This exercise improves the projection and brightness of the voice with minimal effort. It is ideal to perform it by running through different musical notes smoothly to ensure that the full range of frequencies resonates correctly.

Exaggerated vowel scales (A, E, I, O, U)

The final warm-up step integrates articulation with phonation. It consists of pronouncing the vowel sequence (A, E, I, O, U) in a slow and extremely exaggerated manner, stretching the facial muscles as much as possible in each position.

By doing this, we not only warm up the muscles of diction (lips, cheeks, jaw), but also explore the acoustic form of each vowel.

This can be combined with a deep inhalation beforehand and emit all the vowels in one long exhalation, maintaining a steady volume.

This connects diaphragmatic breathing with facial resonance and precise articulation, leaving the phonatory system fully operational and ready for the stage.

Summary

The facial resonators act as natural amplifiers of the voice. The "M" exercise with closed mouth places the sound correctly forward.

Feeling vibration in lips and cheekbones confirms efficient projection. This method enhances vocal brilliance with the least possible effort on the throat.

The exaggerated vowel scale integrates articulation with breathing. Exploring each acoustic form leaves the phonatory system ready for the professional public stage.
