INPUT ARTICLE: Article: 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.

INPUT ARTICLE: Article: Numerous online agencies offer courses in babysitting. Look for an online training course geared toward your needs (such as infant care or early childhood development). Search for an option that fits your budget. Many childcare licensing agencies offer free babysitting courses. Check your local childcare licensing agency's website or call and ask if they have any upcoming courses. Free courses generally do not grant "certificates," however, they may still offer valuable knowledge. Online babysitting courses range from as low as $20 to as high as $200. Although there are many online options for babysitting classes, not all of them may be worthwhile. Look for a company with positive online reviews as well as testimonials from clients. Also, look for a contact telephone number, call them, and ask them some questions over the phone. A company that you cannot reach by phone is probably not a good choice. Some training programs are geared towards students of a specific age. For example, some are created for young adults (usually ages 11-15), while others are for older students. Additionally, some course like you to already have a background in childcare, while others are for beginners. Finally, some courses require you to be fluent in English, while others do not. Be sure you meet any requirements for the course before you enroll. Most babysitting courses are geared toward younger people (often ages 11-17). If you are an adult looking to train in babysitting, search for "advanced" courses. Various courses will have various fees. Some online babysitting classes are as low as $20, and may go as high as $200. Select a course that you feel good about, and pay the appropriate fee at the time of registration. Once you have registered and paid the fee, you simply need to log in and complete the course. Various courses will span different timelines. Most courses can run anywhere from 4 to 12 hours.
