Vocalists, whether performing live or recording in the studio, rely heavily on the health of their vocal cords and the ability to manage their breath for optimal sound quality. Protecting and strengthening the voice is essential to longevity as a singer, and it can drastically improve the quality of recorded performances. Here, we cover key breathing exercises and other vocal health strategies to help singers achieve the best results.

1. Breathing Exercises for Improved Vocal Control

Good vocal technique starts with proper breath support. Breath control affects everything from pitch stability to volume and tone, and improving it can significantly enhance a vocalist’s endurance, flexibility, and tone quality.

a. Diaphragmatic Breathing

Diaphragmatic breathing is the foundation of efficient vocalization because it engages the diaphragm, allowing for deeper, controlled breaths. Unlike shallow chest breathing, it ensures sustained airflow, reducing tension on the vocal cords.

• How to Practice:
  • Place one hand on your stomach and one on your chest.
  • Inhale deeply through your nose, feeling your stomach rise as your lungs fill with air.
  • Exhale through your mouth slowly, focusing on keeping your chest still and letting the abdomen control the breath release.

This method allows for steady air pressure and is essential for delivering long notes and controlling dynamics.

b. Breath Control Hissing Exercise

This exercise helps vocalists improve the ability to control airflow for longer phrases.

• How to Practice:
  • Inhale deeply through the diaphragm.
  • Exhale slowly through your mouth, making a continuous “hiss” sound.
  • Try to sustain the hiss for as long as possible, maintaining an even breath flow throughout.

This exercise strengthens endurance and improves control, which is particularly helpful for holding notes and regulating vibrato in recordings.

c. Lip Trills (or Bubbles)

Lip trills help release tension while developing breath control, vocal range, and resonance.

• How to Practice:
  • Relax your lips and blow air through them to create a bubbling or trilling sound.
  • Glide up and down scales while trilling to help loosen up your vocal cords and increase airflow.
  • Lip trills help smooth out transitions between registers and increase lung capacity for sustained singing.

2. Vocal Warm-ups

Just as athletes warm up their muscles before a workout, singers must warm up their vocal cords to prevent strain and injury. Proper warm-ups also lead to better vocal flexibility, resonance, and recording quality.

a. Humming Scales

Humming is a gentle way to begin a vocal warm-up and encourages resonance in the mask (the area around the nose and cheekbones).

• How to Practice:
  • Start by humming a comfortable pitch and gradually move up and down scales.
  • Focus on feeling the vibration in your nose and mouth, which indicates resonance and vocal placement.

b. Vocal Sirens

Sirens are continuous glides between low and high notes that stretch the vocal range and strengthen control across registers.

• How to Practice:
  • Begin at your lowest comfortable pitch and slide smoothly up to your highest pitch, then back down.
  • Focus on maintaining a consistent tone and breath flow throughout the exercise.

This exercise is great for smoothing out breaks in the voice and transitioning between head and chest voice without strain.

3. Hydration and Nutrition for Vocal Health

A well-hydrated voice is essential for vocal health and recording quality. The vocal cords need moisture to vibrate efficiently and avoid irritation or strain.

a. Water Intake

• Hydration: Drink plenty of water throughout the day. Staying hydrated helps keep the vocal cords lubricated, which allows for smoother phonation and better vocal flexibility.
• Room Temperature: Drink water at room temperature instead of cold water, which can constrict the vocal cords.

b. Vocal Hydration Steam

For immediate hydration, steaming is an effective method. It soothes the vocal cords and promotes recovery.

• How to Practice:
  • Use a personal steamer or simply boil water and inhale the steam. You can add herbs like chamomile for an extra soothing effect.

c. Foods to Avoid

Certain foods and beverages can have a negative impact on the voice, particularly before recording sessions:

• Dairy products: These can create mucus, which affects vocal clarity.
• Caffeine and alcohol: Both are dehydrating and can dry out the vocal cords.
• Spicy foods: These can irritate the throat and lead to inflammation.

4. Vocal Rest and Recovery

Vocal rest is just as important as vocal exercise. Overuse of the voice can lead to strain, hoarseness, and potential long-term damage.

a. Scheduled Rest

Incorporate periods of vocal rest throughout your day, especially after long singing sessions. Allow the vocal cords time to recover, particularly if you’ve been pushing your range or recording for extended periods.

b. Proper Posture

Good posture aligns the body in a way that promotes optimal breathing and vocal projection. Whether recording or performing, make sure to:

• Stand or sit with your back straight, shoulders relaxed, and feet shoulder-width apart.
• Keep your chest open and avoid slouching, which restricts diaphragm movement.

5. Improving Recording Quality with Vocal Technique

Recording environments can sometimes lead to tension or poor vocal habits, especially under the pressure of capturing a perfect take. Here are some tips for improving vocal technique and sound quality in the studio:

a. Microphone Technique

• Distance: Maintain a consistent distance from the microphone to avoid fluctuations in volume and tone. Typically, 6-12 inches is optimal.
• Pop Filters: Use a pop filter to prevent harsh plosive sounds (like “P” and “B” sounds) from overwhelming the microphone.
• Dynamic Control: Use breath support to maintain consistent volume without straining for loud sections or cutting off notes prematurely.

b. Vocal Placement

• Forward Placement: Singing with a forward vocal placement (resonating in the mask) helps create a clear, resonant sound. Avoid “swallowing” the sound or pushing it from the throat.
• Open Throat Technique: Keep your throat open and relaxed to allow the sound to resonate naturally. Tensing the throat can lead to a strained or nasal tone in recordings.

In Sum

To maximize the quality of their vocal recordings and maintain vocal health, singers should focus on proper breathing techniques, warm-ups, hydration, rest, and mindful recording practices. By incorporating these techniques, vocalists can not only protect their voice from injury but also achieve a more resonant, consistent, and controlled sound.
