In one sentence, describe what the following article is about: A vocal range is the span from the lowest to highest note that a voice can make. There are 4 main vocal ranges with several sub-ranges that people can produce. Every person possesses a different vocal range, and while men typically fill out the lower ranges and women the higher ranges, some people possess an ability to span several ranges. The 4 main vocal ranges from highest to lowest are: Soprano, Alto, Tenor, and Bass. Sub ranges include: Mezzo-soprano, Contralto, Countertenor, Tenor 1 or Tenor 2, and Baritone. High tenor is also known as Tenor 1. Middle C is also referred to as C4 in scientific pitch notation on a music scale. Middle C will help you find your vocal range since it's in the middle of the piano or keyboard and a great starting pitch that most people can sing. To locate middle C, look for the name of the piano manufacturer in the center of the piano. You'll see a grouping of 5 black keys in the middle separated by 2 white keys. The white key directly to the left of the 2 black keys in the center of the piano is middle C. You can find your vocal range on a piano, keyboard, or with an app or computer program by singing along as you go up and down in the notes. To accurately find your full vocal range it's best to do some vocal warm ups before you begin to loosen up your vocal chords. Start warming your voice up by humming and allow your pitch to slide up and down freely. Sing scales on lip trills by pursing your lips and blowing air through them as if you were blowing bubbles underwater. Start at middle C and match the pitch. Then progress downward on the piano hitting each note and matching its pitch. Once you've gone as far down as you can and still produce a sound with your voice, make your way back up and continue matching pitch to notes until you've gone as high as possible while sustaining the note. As you go higher up, you will have to sing in head voice and falsetto. Head voice is when you feel the vibrations in your head as you're producing sound from higher up in your body. Think Mickey Mouse when trying to sing in head voice. Head voice marks the break in your voice, where you can't smoothly hit a higher note. Falsetto, or "false voice" is when you feel that nasally pinch in the back of your throat. Once you've gone as low and high as you can, count how many octaves your voice spans. Each octave is 8 notes. Start at middle C and count down to the next C, remembering which is the lowest key you could hit. Repeat with the upper keys. Most people possess a range of 1.5 octaves. High Tenor is in the (G2-)C3-B4(-E5) range. If you naturally sing in the tenor range, you're well on your way to singing in high tenor. Locate middle C again and match pitch with an "Ahhhhh" sound. Now locate the C an octave below Middle C, followed by the C an octave above Middle C. Match your voice to each note by going, "Ahhhhh." Slowly slide between the notes if you have trouble matching the pitch. Note where your throat tightens up or where you need to send more air to hit a note. Slide as far as you can without straining your voice, then back off. Typically the highest note for a tenor is around the E5 key.
Summary: Learn the different vocal ranges. Find Middle C. Locate your vocal range. Practice your tenor vocal range.

Working the night shift can increase your risk for a variety of medical problems, including diabetes, cancer, heart attacks, and obesity. Schedule regular check ups with your doctor to monitor your health and screen for illnesses. Ask your doctor for recommendations for any supplements or lifestyle changes that may help you stay healthy with a nighttime work schedule. Prepare your meals at home and bring them to work to avoid eating vending-machine snacks or other unhealthy foods. Opt for fruits, vegetables, whole grains, low fat dairy, and lean protein. Steer clear of foods that are sugary, high in fat, or spicy, as they can cause indigestion or sluggishness. Aim to eat your main meal of the day in the evening before you go to work. Eating a large meal too soon before sleeping can cause heartburn, gas, or constipation. Eat smaller meals or snacks during your shift or afterwards. Be mindful of how much caffeine you consume in a day to avoid adverse effects. Though it is tempting to drink coffee, tea, and caffeinated soda to stay alert, you should not consume more than 400 mg a day. Avoid drinking caffeine in the four hours before you intend to sleep, as it can adversely affect your ability to do so. Note that 400 mg of caffeine is found in two or three small cups of regular coffee. In addition to helping you stay fit, regular exercise will naturally increase your energy, positively impact your mood, and will also help you sleep better. Instead of going right to bed when you get home from your midnight shift, do some exercise. The morning is an ideal time to work out, and it will keep you allow you to sleep for longer before your next overnight shift. Opt for high intensity cardio like cycling, which will provide an intensive workout and tire you out to ensure better rest afterwards. Working the midnight shift might mean that you are lacking essential vitamins, such as Vitamin D. Ask your doctor if vitamins and supplements (e.g., melatonin) are a good option for you. Purchase daily multivitamins over the counter at your local pharmacy for a good overall health boost.
