In past posts, I have decried the use of vocal fry (explained perfectly in this video). Actually, in researching how to heal an overused voice, I found suggestions to use a bit of vocal fry to help heal as the voice heals best when used gently to keep the blood flowing etc. Well, I was intrigued.
Here in this video, the use of vocal fry or creak is illustrated. As in all things, moderation is the key. Judicious use of fry is helpful but to use it all the time as some current singers seem to be doing will cause you to lose much of your range.
I will listen differently to a lot of music differently after this tutorial.
