As a keen amateur singer, this simple device has opened a much welcome door for me in my learning. Blowing down the tube while phonating opens my throat to the ideal shape and size for good singing. In so doing, it makes my abdominals the prime driver of breath and effort, not my throat. By remembering the physical sensation of how my throat feels, I can replicate it without the tube in my subsequent singing. I know more or less if I’ve remembered the correct physical technique when I sing, because my abdominals will be doing the work, with my throat doing no other than staying open and clear. This helps me to sing for longer whereas before I would tire very easily.

Additionally, I have a tendency to over-articulate consonants which does little for legato singing, and also makes singing more tiring. However, using the tube helps me to correct this because my adjusted throat and mouth position favours vowel sound delivery, with my lips doing the minimum required to form the obstructive consonants. So it helps me sing a smoother line.

Lastly, after practising with the tube, both for warm-ups, and to run through individual songs, I find my tuning is much more accurate because it obliges one to sing with a good physical technique ie good abdominal support and open throat. I usually end a song in pitch. As a singing aid, I think it’s utterly brilliant and a vital tool in assisting the singing process.
