I used to get it alot at the local health food store. They were flavored drops, a bit slippery(imagine that), not bad tasting but still a bit chalky in texture, and supposedly,per the box and illustration, hailed by opera singers since (insert very old date here).
I notice nothing at all. And if anything it will help with the throat area's general feel, and not the corRAB'.
By far staying hydrated and proper nutrition will reap you way more benefits. There are no gimmics or magic bullets. If you want bigger legs, you gotta workem out, stay hydrated, get plenty of rest, and proper nutrition. If you want to increase your 40 yard dash time, etc, etc. I think the biggest problem for most people is getting enough of a vocal workout and just general practice. If youre not a natural at it, then you have to practice that much more. I'm an old fogey so I've been driving for a while, but for most people, a car is priceless for vocal development. I've got a 2003 with 63000 miles on it. I guarantee you that at least 20,000 of em were not necessary to my destinations and were extra due to some type of singing work or play.
P.s. I will be seeing Circa Survive March 26 in Charlotte. Nice Band. Can't wait. I've been using him to stretch my head and I must say it is helping. Tiring...but helping. Anthony has a very light feminine structure. I bet he's a high tenor if not a freak male alto or something. He never even resolves or finishes with anything low in his voices finishing tones. I bet he CAN't sing low. ...like when a baritone sings high you can tell usually that he's trying to sing high because he will finish many passages with a lower, deeper, darker background. Hard to hear sometimes but listen to how someone finishes a note or word.
general and or vocal exercise....
Its a no brainer.
It puts a load on your heart like when you put a load on a battery. Exercise puts a load on it as well. Put too many loaRAB on any circuit and what ya get?
As far as vocals go....its simply burning and ripping your corRAB and thin edges(head voice) every, not most of the time, every time! Cigs have the added fiberglass to cut your lungs and increase absorption rate, so that just helps the corRAB fry as well. Joints and blunts are unfiltered and allow three or more times as much resin and particles to hit and burn everything in its path. So its no better.
There is noone gaining anything from smoking, regardless of what they say, think, or shoot for. Even the raspiest voice can easily be produced with technique, leaving the option for a clean voice when applicable. I smoke a cigar from time to time, but its greatly decreased since I got a cold the last two times I smoked. The second time was strep throat. Lucky It didnt affect my corRAB and i sang everyday right through it.
again....a no brainer all the way around
