This is ALWAYS my first vocalize because it focuses on breath control and tone support. It is done slowly and held as long as you can to empty the air completely. The air is then PULLED IN deep into the lungs by the action of the diaphragm. This is your FIRST and most important objective in warming up your voice.
Performed in the middle register it avoids straining muscles. Do it as long as it takes until you feel the action of the diaphragm. Not too high, not too low in the range.
The staccato is a great exercise that allows the singer to observe the initiation of sound, the attack. Put a silent H in front of the vowels so you do not crack the sound in what we call the glottal attack. The vowels SIT on the diaphragm.
The lalala exercise is to relax the jaw and bring the tongue forward in preparation for great pronunciation. The tip of the tongue is extremely instrumental in relaxing the throat and freeing the vowel.
The chest resonating area is not a place where you sing. It is where the beautiful rich colors of the voice vibrate. We awaken the space by going to the lower register and observing and feeling it vibrate.
Yawning is a great exercise to open the space at the back of the throat and relax the jaw. Brrrr or Drrrrr is very difficult for some people and easy for others. Try it and have fun.
We awaken the mask area that is the mouth, palate, teeth, tongue including the space behind eyes to bring brilliance and sharpness of the tone. The mask that is well developed is an expression of who we are and what we show to the world.
I always awaken the Head Resonating Area at the end of a workout because we need to have GREAT breath control, flexibility of the voice box and all muscles involved.
We must open the space behind the hard palate, while standing the tone or pitch or sound DOWN on the diaphragm and keep mask and chest resonant also while not pushing.
Have Fun and keep practicing!
