Making bubbles
When you place a bubble tube, glass straw or Lax Vox in a bottle of water and make sound, pressure is applied to your vocal cords in a different way.
Normally, when you create sound, you push air from your lungs, past your vocal cords, and outwards—this creates subglottic pressure (pressure from below).
But with a bubble tube, you actually create supraglottic pressure (pressure from above). The air you exhale has to push through the resistance of the water, making it harder for the air to escape. This creates pressure above your vocal cords—and it feels amazing!
Why it’s beneficial:
✔Your vocal cords vibrate in a more relaxed, controlled way.
✔The exercise gently warms up your vocal cords with minimal effort.
✔It’s also a fantastic tool for vocal recovery, giving your cords a gentle “massage.”
How it helps:
✔You produce sound with less effort, minimizing strain.
✔Bubbling helps you feel whether you can sing a melody comfortably.
✔If you can bubble through a melody but struggle to sing it, that’s a sign you just need to improve your technique.
✔If you can’t bubble through high notes, it indicates that you need to work on expanding your vocal range first.
