This is a FANTASTIC device to help rest, relax, and therapeutically restore the voice. As a professional opera singer for over 25 years I’ve tinkered with a variety of different straws to use SOVT exercises, but oftentimes the straws you grab are made of paper (great for the environment, but I HATE them), or too small or too large! The Vocal Trainer does everything that any straw can do, but it allows you to personalize the amount of resistance to the breath that you’d like to sing with. The greater the pressure, the more I find it helps with truly realizing that you are physically in the appoggio. Its a great device that I wish I had known about years ago!
