While promoting her role within the upcoming film adaptation of the Broadway hit “Evil”, singer Ariana Grande made a podcast appearance The left lots of her fans confused and frightened.

In the center of the interview, the sound of her voice modified drastically; she went from a deep and barely croaky voice to a much higher voice with a soft, light texture.

Speculation arose.

“That was such sudden help,” shouted an Internet user“It’s her alter ego kitten programming,” joked one other fan. Others wondered if Grande stuck in Glinda's voicethe character she plays in “Wicked,” who speaks with a softer intensity and better pitch. (After Austin Butler played Elvis Presley within the musical “Elvis”, the young actor continued, speaking just like the King of Rock and Roll long after the premiere of the film.)

Grande finally responded added to the confusion, explaining that she frequently and intentionally changes her “vocal posture” to keep up her vocal health.

For those unfamiliar with the science of voice production, Grande’s explanation can have caused more – quite than less – confusion. But as a speech therapist As a physician specializing in voice disorders, I understand how effective these techniques may be.

Singers and actors who frequently overstrain their vocal cords can suffer from what’s often known as “Phonotrauma“ or excessive and inappropriate use of the voice.

The data shows that voice disorders can result in: Loss of labor for everybody, not only singers. But skilled singers – whose livelihood, like that of skilled baseball pitchers, is dependent upon a completely functioning a part of their body – usually tend to experience financial and emotional distress from a voice disorder.

Cables on a collision course

So that you simply speak or singYour vocal cords—a fragile pair of thin, muscular V-shaped strips in your throat—must come together and vibrate against one another as air is pushed through out of your lungs.

As the strain and length of the vocal cords increases, they vibrate faster, leading to a rise in pitch. As the strain and length of the vocal cords decreases, they vibrate slower, leading to a decrease in pitch.

The more an individual uses their voice, the more often the vocal cords collide with one another. For example, when Steven Tyler sings at the tip of “Keep dreaming”, his vocal cords vibrate over 800 times per second. For comparison: a hummingbird beats its wings about 70 times per second.

Many well-known artists go on long tours where they perform night after night and infrequently have little time for vocal rest and rest. It isn’t any wonder that lots of them find yourself injuring their vocal cords. There are other habits and behaviors that may damage the fragile mechanism that produces a singer's unique sound: poor weight loss plan, lack of sleep, shouting, smoking and alcohol consumption.

An operation entails risks

For Grande, the pain of losing her voice is nothing latest.

In 2013, She suffered a vocal cord hemorrhagewhich occurs when a blood vessel within the vocal cords ruptures attributable to phonotrauma. Doctors ordered strict vocal rest so she could get better.

However, vocal cord injuries don’t all the time heal on their very own. Surgery could also be obligatory, but this feature often carries significant risks for singers.

Surgical procedures can result in a lack of vocal range attributable to scarringIn 1997, Julie Andrews lost her crystal clear singing voice, which once over 4 octavesafter a minor operation on the vocal cords.

Fortunately, not all vocal cord surgeries end in disaster: Grammy winner Adele went under the knife in 2011 to remove a vocal cord polyp. More than a decade later, she continues to top the charts. In fact, there are lots of singers, actors, news anchors and talk show hosts who are suffering from various vocal cord injuries and complaints and were in a position to successfully proceed their skilled careers.

But athletes who don’t change their habits and behavior after an injury or successful surgery may find yourself right back where they began.

Prevention is the very best medicine

With that in mind, Grande's attempt to scale back the chance of a vocal cord injury that might jeopardize her skilled success is a brilliant one.

But how exactly does she achieve this by changing the sound of her voice as she speaks?

Responding to social media speculation, she stressed the importance of adjusting her “vocal position” to keep up her vocal health.

What she's actually talking about is the interaction between the vocal cords and the vocal tract, which incorporates the throat, nose, and mouth. The vocal tract acts like a filter for the sound produced by the vocal cords, dampening some sound waves and amplifying others. This interaction creates an individual's unique, recognizable voice.

When Grande focuses on raising her voice higher in her vocal tract—toward her nose—certain vibrations produced by her vocal cords are amplified by the air-filled cavities in her brow, making a brighter, higher-pitched sound that really reduces the strain on the vocal cords themselves.

In the clip, Ariana's voice also sounds light and barely breathy. She achieves this by reducing the force applied to her vocal cords, which can prevent them from closing completely when she speaks.

By making a small space between the vocal cords, they’re prevented from violently colliding with one another, which in turn can prevent phonotrauma. This will not be to be confused with whispering, which can be harmful to the voiceas this will put strain on the vocal cords and neck muscles.

As with many health issues, prevention is commonly the very best medicine. Although behavior change may be difficult, Grande appears to be up for the challenge.
