Here you see a lovely student demonstrating siren slides of a fifth which can be used as a warm-up on the phonation tube.

Notice how important it is to take time over the siren and to make sure the facial muscles are relaxed.

Hi I’m Harriet. I really benefit from using the phonation tube – it helps to open my throat and stops me from squeezing which gives me a better over-all sound and it takes the stress off my voice and makes it easier and more enjoyable to sing.
