Is a Vocal Warm-Down Important?
Vocal warm-ups are important to get your laryngeal musculature ready for excessive use, by gently bringing blood flow to the muscles. But after these vocal acrobatics a 3 hour show with 2 encores (or aria after aria), should you “warm-down?” Most of the vocal damage in a trained performer happens after the show, during after-parties and interviews, where the performer is having to talk loudly for a long period of time over loud noises of crowds or parties.
So, should you take a voice rest after performing?
According to this study by Verdolini et al. it was found that resonant voice production (easy phonation associated with front of the face vibrations in sound production) after a period of extended voice use, was useful in reducing acute vocal fold inflammation.
So, how could it ever be helpful to vocalize after you have already been vocalizing at high intensity?
This study suggests that voice rest is helpful as well, but resonant voice production is even more beneficial in lowering inflammatory mediator concentrations at 24 hours post. So get to humming after a performance. It could benefit your vocal folds.
