What made Freddie Mercury’s voice so magical? His teeth

The singer believed his buck teeth gave his voice the special resonance. Scientists now think there was another reason.

Every year, one cannot help remember Freddie Mercury on September 5, his birthday. And while one obviously looks back on his dazzling frontmanship, it is his vocal pyrotechnics that echo in one’s ears.

Reputed to have that rare four-octave vocal range, Mercury’s voice could escalate, within a few short bars, from a deep, dark growl all the way up to a bright, shining coloratura (via various chromatic shades of tenor). Rolling Stone ranked Mercury 18th on its list of the Greatest Singers of All Time, but many fans, as well as rock critics, would angrily take to the streets to protest that lowly ranking. To hear Mercury sing Bohemian Rhapsody or Killer Queen is to understand.


In his first band at school in Panchgani, the Hectics, the buck-toothed Mercury was known as a crazy singing piano-player who was inspired by Little Richard – but the band’s real star was another child named Bruce Murray. It was only in later years that Mercury’s voice developed fully into what rock journalist Caroline Sullivan once described as “a force of nature, with the velocity of a hurricane” – a voice that cut, almost God-like, through Queen’s mix of Brian May’s guitar, cranked up to 10, and Roger Taylor’s blasting drums.

But what exactly was it that made Mercury’s voice so unique?

Mercury believed it had something to do with his buck teeth, and the special resonance that their configuration gave to his voice. This was paradoxical, because he had been terribly self-conscious about his teeth since childhood (having been cruelly nicknamed Bucky by schoolmates) – and yet he refused to get orthodontic treatment to fix his malocclusion, fearing that it would rob his voice of its special magic. To try and disguise the problem, he grew his trademark mustache, and even developed the poignant habit of holding his hand up to his mouth when talking to people.

Last year, a team of European scientists set out to discover a scientific explanation for the magic of Mercury’s voice – or specifically, as they put it, “to develop an acoustical analysis of his voice production…based on a perceptual and quantitative analysis of his sound recordings”.

Unique ‘vestibular folds’

The scientists first analysed a body of Mercury’s music, including Freddie Mercury: The Solo Collection and 23 other recordings. Then, particularly intrigued by the distorted notes Mercury produced to create his signature growl sounds, the team did a unique simulation exercise: selecting rock singer Daniel Zangger-Borch to simulate Mercury’s singing voice, they filmed his larynx with a high-speed endoscopic camera as he pushed his vocal system into overdrive.

The team’s report, published in the journal of the British Voice Association, is, expectedly, filled with abstruse audiological terms like “subharmonic phonation” and “mean fundamental frequency modulation rate”. But what it essentially boils down to is this: Mercury was probably not a natural tenor, as we generally believe, but a baritone who sang as a tenor, using exceptional voice control.


The report then went on to reveal that Mercury produced his singing voice in a way that is markedly different from other singers: he did this by not merely vibrating his vocal cords, but also activating his vestibular folds, a pair of mucous membranes located just above the vocal cords. These membranes are called “false vocal cords” because they are usually not involved in the production of voice. But, by mobilising them, Mercury created a rare audio phenomenon called “subharmonic vibration” – which is what gave his voice that signature growl.

Strangely, however, the study seemed unable to verify Mercury’s legendary four-octave range, saying that from the analysed data it could neither conclude, nor rule out, the possibility of such a phenomenon.

And what about Mercury’s belief that it was his buck teeth that gave his voice its magic? The report makes no mention of this, but experts are divided in their opinion on this. So it is just as well that he never risked his multi-million dollar voice with orthodontic treatment.


The big ‘What if’?

The great what-if that we can’t help asking today is: what if Mercury hadn’t died when he did? What would he have gone on to do with his fabulous voice, and prodigious talent?

Opera singer Montserate Caballé, with whom he collaborated on Barcelona, says that in his last years Mercury was exploring his passion for classical music, and that the two of them had, in fact, talked of working together on The Phantom of the Opera. Tim Rice, who co-wrote some of the lyrics of Barcelona, adds that given the way he was going, Mercury might have even evolved into a great writer of opera.

So what would that have meant for the future of Queen? Some close friends, like Tim Rice, believe that no matter what avatar the restless Mecury morphed into next, he’d have never abandoned Queen. But, others like his long-time aide, Peter Freestone, dismiss that idea, insisting that “he hated the idea of bands getting back together. Oh, no, no, no.”

But who knows?

Till the very end, Mercury pushed his voice to the limit. When Queen was recording The Show Must Go On, just before he died, Mercury was so ill he could hardly walk. But, as Brian May recalls, “He went, ‘I’ll f***ing do it, darling’ – vodka down – and went in and killed it, completely lacerated that vocal.”

Why do our clothes fade, tear and lose their sheen?

From purchase to the back of the wardrobe – the life-cycle of a piece of clothing.

It’s an oft repeated story - shiny new dresses and smart blazers are bought with much enthusiasm, only to end up at the back of the wardrobe, frayed, faded or misshapen. From the moment of purchase, clothes are subject to wear and tear caused by nature, manmade chemicals and....human mishandling.

Just the act of wearing clothes is enough for gradual erosion. Some bodily functions aren’t too kind on certain fabrics. Sweat - made of trace amounts of minerals, lactic acid and urea - may seem harmless. But when combined with bacteria, it can weaken and discolour clothes over time. And if you think this is something you can remedy with an antiperspirant, you’ll just make matters worse. The chemical cocktail in deodorants and antiperspirants leads to those stubborn yellowish stains that don’t yield to multiple wash cycles or scrubbing sessions. Linen, rayon, cotton and synthetic blends are especially vulnerable.

Add to that, sun exposure. Though a reliable dryer and disinfectant, the UV radiation from the sun causes clothes to fade. You needn’t even dry your clothes out in the sun; walking outside on a sunny day is enough for your clothes to gradually fade.

And then there’s what we do to our clothes when we’re not wearing them - ignoring labels, forgetting to segregate while washing and maintaining improper storage habits. You think you know how to hang a sweater? Not if you hang it just like all your shirts - gravity stretches out the neck and shoulders of heavier clothing. Shielding your clothes by leaving them in the dry-cleaning bag? You just trapped them in humidity and foul odour. Fabrics need to breathe, so they shouldn’t be languishing in plastic bags. Tossing workout clothes into the laundry bag first thing after returning home? It’s why the odour stays. Excessive moisture boosts fungal growth, so these clothes need to be hung out to dry first. Every day, a whole host of such actions unleash immense wear and tear on our clothes.

Clothes encounter maximum resistance in the wash; it’s the biggest factor behind premature degeneration of clothes. Wash sessions that don’t adhere to the rules of fabric care have a harsh impact on clothes. For starters, extra effort often backfires. Using more detergent than is indicated may seem reasonable for a tub full of soiled clothes, but it actually adds to their erosion. Aggressive scrubbing, too, is counterproductive as it worsens stains. And most clothes can be worn a few times before being put in the wash, unless of course they are sweat-soaked gym clothes. Daily washing of regulars exposes them to too much friction, hastening their wear and tear.

Different fabrics react differently to these abrasive agents. Natural fabrics include cotton, wool, silk and linen and each has distinct care requirements. Synthetic fabrics, on the other hand, are sensitive to heat and oil.

A little bit of conscious effort will help your clothes survive for longer. You can start by lessening the forces acting on the clothes while washing. Sort your clothes by fabric instead of colour while loading them in the washing machine. This helps save lighter fabrics from the friction of rubbing against heavier ones. It’s best to wash denim materials separately as they are quite coarse. For the same reason, clothes should be unzipped and buttoned before being tossed in the washing machine. Turning jeans, printed clothes and shirts inside out while loading will also ensure any abrasion is limited to the inner layers only. Avoid overloading the washing machine to reduce friction between the clothes.

Your choice of washing tools also makes a huge difference. Invest in a gentler detergent, devoid of excessive dyes, perfumes and other unnecessary chemicals. If you prefer a washing machine for its convenience, you needn’t worry anymore. The latest washing machines are far gentler, and even equipped to handle delicate clothing with minimal wear and tear.

Bosch’s range of top loading washing machines, for example, care for your everyday wear to ensure they look as good as new over time. The machines make use of the PowerWave Wash System to retain the quality of the fabrics. The WaveDrum movement adds a top-down motion to the regular round action for a thorough cleaning, while the dynamic water flow reduces the friction and pulling forces on the clothes.


The intelligent system also creates water displacement for better movement of clothes, resulting in lesser tangles and clothes that retain their shape for longer. These wash cycles are also noiseless and more energy efficient as the motor is directly attached to the tub to reduce overall friction. Bosch’s top loading washing machines take the guesswork away from setting of controls by automatically choosing the right wash program based on the load. All that’s needed is a one-touch start for a wash cycle that’s free of human errors. Read more about the range here. You can also follow Bosch on Facebook, Twitter and Instagram.
