Why do I alternate between straight tone and vibrato?
Tuesday, March 9th, 2010
Andrew, 24, says: I’ve studied privately in the past before, but I currently can’t afford a tutor. Lately, I’ve been noticing that it’s much harder to maintain an even, easy vibrato when I descend down a scale. I often briefly go into a straight tone, though I can usually maintain my vibrato if I concentrate. Can you tell me why this might be? Thanks!
ANSWER: Andrew, your question is a good one, however, it is one that can only be answered with any assurance of being appropriate for you personally by a voice teacher who sees and hears you in person. So, what I offer you below may sound a bit “academic” and you will need to sift through to see what, if any, applies to you.
A consistent pleasing (fairly rapid) vibrato is normally a result of good coordination between the muscles related to phonation (making sound), and the mechanism of respiration. If you find that on the descent to lower notes there are some tending to straight tone, then the likelihood is that there is an imbalance taking place. Be aware, that as pitch descends, so also should respiratory support and vocal resistance - incrementally - little by little in a continued “balancing act” of vocal coordination that at the same time does not diminish clarity and resonance. A tendency of many young untrained singers, or singers beginning training is that once the high note has been achieved, they seem to “freeze in place” maintaining the same energy and space with nothing changing on the descent to the lower notes again. But in fact, we singers have to learn to stay flexible and ease up on support slightly as pitch descends as well as allow our oral space to diminish. In other words, when we’ve revved up our physical engines to 3,000 rpm for the high note … we need to lower the rpm incrementally for the notes an octave lower, thereby keeping the balance and energy consistent. Besides applying the principle of incremental energy per pitch (the higher the more, the lower the less), I’d suggest that you “memorize the feelings” you experience when you have that pleasing vibrato … and then work to reproduce those feelings throughout your range.
While I would not be overly concerned about what you have described, it does cause me to ask whether or not you are and have been staying physically fit. (You don’t need to tell me.) If you were once “in shape” but now live a sedentary life style, this will affect your energies … and your vibrato. Even 40-minutes of exercise (that gets the heart pumping to 120+/minute and the sweat glands open) every day will help the process of keeping everything else in better working order.
You possess a sensitive perception of your own sound Andrew, having made note that you occasionally lose vibrato. However, I’d like to encourage you not to become too “introspective” or “paranoid” about the little anomalies. If you are singing a quickly moving descending scale passage … the sense of “slipping into straight tone” may be just fine. Perhaps a good thing to do would be to have a well trained singer listen to you to confirm or deny the validity of your concern.
One last tidbit: the answer may be as simple as you performing some flexibility (fast moving) vocal exercises on a daily basis for a period of time, until you find yourself negotiating similar passages in the literature with the same energy.
I’d be interested to know if any of the scenarios “rang a bell” with you.
Best wishes.
