I favour a warm-up for the voice which helps to gradually bring it into full use. Over the years, both as a jobbing opera singer and a singing teacher, I have come to rely upon the five-note pattern as an excellent provider of my requirements. I want something to offer a gentle stretch but not over too wide a range of notes and which has the capacity to challenge breath control. As an open-voiced exercise, it can be used to check that vowels remain the same quality throughout the range, to encourage a seamless legato with no aspirations in between each note and to focus on intonation or even resonance. In the music we need to sing, we often come across scalic passages or stepwise intervals, therefore this warm-up also serves as a technical exercise to set up good muscle-memory which means we can focus on something else, leaving the voice to instinctively know how to sing those types of passage.
In the video, Georgie, a teenage student uses the phonation tube to sing the five note warm-up. You’ll notice that here we have used a pint glass which means it’s really easy to see her breath output – if this falls, we know that her support is not working as well as it needs to. In the glass, there is quite a large depth of water, this makes her breathing support muscles work harder (the less depth, the less resistance and the easier it is). Working with the tube we are looking for bubbles, for air flow and to provide pressure above the cords to help them close more efficiently without the pressure underneath the cords becoming too much – essentially balancing the pressure both sides of the vocal cords. Abdominal support is added cumulatively as we approach the end of the breath. The sound output is quite small in this instance as producing a large sound is not the point of the exercise. We’re aiming for an unbroken legato which is in tune and easy to produce. In the course of a minute, the voice is taken gently across an octave and through the upper passaggio. During the tube use, it lets the student focus on other issues rather than the sound they are producing. These issues can be breath focussed or on the shaping part of the technical process, where we attempt to consciously open the back of the throat fully to create space for the free vibration taking place.
After this exercise we might try the same exercise again, without the tube, trying to recreate the freedom the tube characteristically gives and to replicate any of the lessons learned by tube-use, whatever they may be, on each occasion.
