If you’re a singer, your body is your instrument. Improper care of it over long periods of time will become evident in the sound of your voice. Younger bodies, having less cumulative exposure to external influences, are more resilient. But with each passing year, your body will manifest the signs of these deteriorating influences. In this vocal tip, we’ll address an influence that has proven to be significantly detrimental to the novice as well as the trained and experienced singer.

How Alcohol Affects a Singer’s Voice.

I encourage you to read this with objectivity. This isn’t a lecture on morality. If you like drinking alcohol and think you can’t get through a gig without it, I hope you will consider the merits of this information and use it to your benefit.

Alcohol-Nutrient or Poison?

Even though you ingest alcohol like any other liquid, it is not a nutrient like water, protein, carbohydrates, etc. In fact, your body recognizes alcohol as a poison and works hard to remove it from the system. Any drug is a poison with a small amount acting as a stimulant, giving you a “high;” a larger amount acting as a sedative, making you sleepy and a large enough quantity killing your body.

To rid itself of this poison, the body releases fluids to wash it out, thus increasing urination and dehydration. While alcohol is detrimental to singing, its effects are shorter term than pot (marijuana) and other drugs. Being water soluble, your body can flush the alcohol out faster than oil soluble substances. If you want an alcoholic beverage, it is best to have it after your performance. Then drink a lot of water and allow about 24 hours for your body to fully regain normal fluid levels before you sing again.

The Effects on a Singer of Drinking Alcohol.

Have you ever tried to sing while your mouth and throat were dry? If you have, you probably already understand that the muscles and mucous membrane that compose your vocal folds require hydration to perform well. These vocal tissues make many small rapid motions and adjustments in order to produce the variety of sounds you imagine when you sing. Their flexibility and agility depend to no small degree upon their level of hydration (water content).

You might think that because the vocal folds are covered by a mucous membrane – similar to the tissue of the inside of your mouth – that mucous would help you sing. Unfortunately, abnormal mucous production occasioned by alcohol consumption only reduces vocal fold flexibility and increases the need to clear your throat. Alcohol irritates and dehydrates the vocal folds as well as the rest of the body. To protect itself, the body produces mucous much in the same way as it would deal with an allergic reaction.

Dilated blood vessels and capillaries, another possible side effect of alcohol consumption, may interfere with normal blood flow to the folds and larynx. Without getting further into scientific detail, you probably already understand that this may interfere with the proper function of your vocal instrument.

Perhaps you like a drink before performing in order to relax any stage jitters you may be feeling. Certainly relaxing your body and mind can’t be a bad thing. Perhaps not, but an unwanted consequence is impaired muscle coordination and reduced physical efficiency of your vocal folds. Remember, those little muscles in your larynx perform many rapid subtle actions to produce all the nuances of the vocal tone of which a voice is capable. Even a slight loss of muscle coordination can result in singing off pitch.


A little known fact, in addition to all these insidious influences, is that alcohol depletes your body of B vitamins which are essential nutrients for the proper function of your nervous system. Since your nervous system monitors your muscles, alcohol is like a double-edged sword. It simultaneously impairs motor control via the nerves while reducing the flexibility of the vocal folds via mucous and dehydration.

Last but not least, alcohol can have a numbing effect on your throat thereby reducing your awareness that you are using too much force when you sing. You may be forcing out too much air or otherwise straining and not being aware of it you wouldn’t do anything about it. But let me tell you that by the end of the night or the next day, you will be aware of the negative repercussions of singing with a dehydrated and forced voice.

Is it Worth It? 

So now that you know some of the facts, ask yourself, “Is it worth it?” Is that momentary euphoria worth the consequences to your voice and career? If you have made the mistake of singing and drinking alcohol, especially in a loud nightclub, you should help your body recover by drinking lots of water or vegetable or fruit juice (no sugar added) to re-hydrate the tissue. Take some vitamins, rest your voice and do light vocal warm-ups to limber your vocal muscles. Steaming your voice is a soothing treatment for hydration and clearing out mucous build-up in your larynx. Steaming is a helpful remedy for vocal fatigue even when you haven’t been drinking.
