Does weight affect your singing?
Obesity may be associated with increased tissue bulk in the laryngeal airway, neck, and chest wall, and as such may affect vocal function.
Does Your Voice Change When You Lose Weight? On the flip side, losing weight may lighten your voice if you're a female and deepen your voice if you're a male. If you're not losing a dramatic amount of weight, likely, you won't notice a difference at all in your voice.
There isn't a prototype for how a singer should look; people of any size and shape have the potential to be a good singer. Female singers in particular often face pressure to look a certain way, but being healthy and happy is the most important thing. Musical ability is infinitely more.
Weight loss can cause changes to the overall shape of the larynx, which can affect the voice. If a person loses a significant amount of weight, particularly in the neck or throat area, it can cause the larynx to become smaller, which could result in a deeper voice.
One holds that a large amount of fatty tissue surrounding the voice box (larynx) increases its resonance capability and thus produces a more pleasing sound. The amount of this fatty tissue varies from singer to singer.
Absolutely not. Excess fat will not magically add to your singing ability. The amount of body fat is not related to the singing ability, the vocal apparatus or the breathing capacity in any direct way.
Often, extra fat in your face is the result of excess body fat. Losing weight can contribute to fat loss and help slim down your body and face.
Losing 20 pounds might not make a huge difference in your physical health, but it can lower the risk of contracting obesity-related diseases. You will feel a change in your mobility, meaning you'll be able to run and walk faster.
Studies indicate that too much body fat limits the performance of your voice. Vocal range, voice quality, and vocal aerodynamics all deteriorate when you carry too much weight. Obesity doesn't just change your voice, but it can also change how you feel about yourself.
It's never too late to start singing! In fact, the human voice continues to mature throughout life, so students of any age can benefit from singing lessons. Plus, singing can be an effective way to keep your mind and body sharp.
What is the best age to be a singer?
Once you're 18 years old, your voice should have settled into its adult sound. This means you won't have to sing through the vocal changes of puberty. You can begin at any age of course, but this is as good a time to start as any. So if you're 18 and want to start a career in music, don't delay, begin today!
Having excess fat on the body can also place weight on your diaphragm and chest cavity, which can affect how you sound and how often you need to pause to inhale when you speak. If you have a fleshy face, the fat surrounding your nose and your neck can also create differences in the way you sound.

Studies have shown slight voice changes in extreme weight gain/loss and attribute this mainly to hormonal changes.
Belly breathing, also known as diaphragmatic breathing, helps you access a deeper pitch. This breathing style lets your diaphragm reach its lowest position, which helps slow down vocal cord frequency. Try standing straight, breathing in deep through your nose, and feeling your ribs expand.
Sean Hutchins, director of research for the Royal Conservatory, recently told British newspaper The Guardian that only around 2 percent of the human population doesn't posses the skills needed to determine the right pitch to perform a song.
Exposure to the right kind of music and sounds in these years helps to develop a higher IQ in the teenage years - this, in turn, helps the child to get better grades in school, better years, helps develop memory. Music helps to develop verbal memory, reading skills, and mathematical skills.
As you enter your 60s and 70s, your voice starts to change. Your vocal folds weaken, cartilage in the larynx begins to ossify, and your respiratory system (which helps power your voice) begins to work less efficiently. The result? Men's voices go up, and women's go down.
Because a singer will go without food for as many as five hours from the time he/she arrives at the theatre to the time he/she leaves, they usually feel starved and dehydrated after the performance. They then go out and eat, and go to bed on a full stomach.
Weight lifting is good for singers, but…
A singer needs strong pectorals and abdominal muscles to support the singing voice. The pectorals are the only muscles that anchor the larynx, so having strong pecs improves strength, smoothes the “break,” and provides a rounder, less nasal tone.
The Reasons Singers Go Flat
They're not getting off the consonants and onto the vowels quickly enough. They're swooping and sliding up to words and/or vowels. There isn't proper support and placement. The song/notes/runs are too high for them.
Why do heavier people have better voices?
the correct answer is that overweight people often require more effort in breathing and daily speech. a study found the overweight group within a sample had significantly stronger sound pressure in their regular speech vs avg and skinny people.
Walking remains the single most recommended exercise for singers. Maintain a brisk enough pace to reach your training zone. Swimming has been called the best all around exercise for singers; however, many people develop sinus or ear problems from swimming. Also, be careful not to overtrain.
Pushing your abdominal muscles inwards to sing pushes the diaphragm up prematurely, causing an excess of air to be pushed out of the lungs prematurely which means you end up out of breath more quickly and with a much airier, less resonant sound.
