What Are the Best Songs to Sing for an Audition

What Are the Best Songs to Sing for an Audition Sign up successful Step 2: Know Your Range Nothing will hurt you more than if you’re struggling with notes that are too high or too low for your range.  Comfort is essential. Understanding basic music theory can help you, too â€" that way, if there is a song you like that’s just out of range, you can adjust it to a better key for your voice.  You can always practice and improve your range, also, but expect that there is a place that will always make your voice magical.  Find that spot, and pick music that helps you blow the audience away! Step 3: Know Your Appealing Quirks Some people love the rasp, others the trill.  Maybe you have a rich tone that doesn’t need an abundance of vibrato, or a simplistic but pure voice that shouldn’t attempt bold runs.  There is usually something about our favorite singers we like to point out: they never miss a note, their rich baritone is smoother than butter, their falsetto is unbelievable, the gravel in their voice speaks to you, or maybe the emotion is so strong it makes you tear up.  Many singers have quirks that make them stand out in a good way, like Mariah Carey’s amazing range, Kurt Cobains angsty growl, or Ella Fitzgerald’s clear-as-a-bell-never-overdone perfection.  Others make you crazy because their voices are consistently over-embellished.  Go ahead and find your appealing quirk, and make sure you incorporate it into your audition song. Step 4: Know Your Audience Do a little research before an audition and before choosing your audition song.  While you don’t want to lose yourself or your individuality by choosing a song you think the panel of judges wants to hear, you still shouldn’t go so far off the grid that they don’t want to listen. Find a happy medium, and choose a song that fits you and the audition.  It’s natural that if you twang that you should consider country or a pop-country cross.  If youre a first soprano heavy on the vibrato, opera probably fits better.  Also, who are you trying to impress? Auditioning for a high school theater production is going to require a different song choice than auditioning for a Broadway musical.  The judges may be at different experience levels, as well.  What might wow your high school music teacher is probably not going to be the same for a producer in New York.  And taking a risk with a bold, complex song choice might work in New York, but it might be too much for your high school.  Look at what you’re trying to achieve, who the audience is, what the experience level of the judges is likely to be, and what they might be looking for. Step 5: And Finally…Choose the Right Song for Your Audition If you’re not connected to your song, chances are the audience and judges are going to know it.  Ditto if the song is too complex for your experience level.  If the song doesn’t fit your tone, range, and quirks, consider selecting a different one. Music is an intrinsically personal thing.  Choosing a song to audition with means you should be able to convey the emotion it stirs in you, and add enough of your style to make it your own.  It should fit who you are, and who you want to be musically.  If you’re not a bounce-around-the-stage type of singer, then choose something slower.  If you’re upbeat and joyous, then go with a song that’s a little more fun. Lastly, try to avoid the songs that you know everyone is going to sing.  Sometimes judges get sick of the “it” songs.  Be the person who stands out and is a breath of fresh air! For more information, check out the tips in the video below for musical theatre auditions- Some Final Thoughts Enlist the experts â€" Never be afraid to ask for help!  Even seasoned performers have vocal coaches, who often help them select the best songs to sing for an audition.  Working with someone with the skill and background to make you a better singer might just be the boost you need to win the audition.  Plus, you can use those voice lessons to get more pointers and practice before the big day. Stick to your experience level â€" It can’t be said enough: if you’re not Adele, don’t try to be. Practice, practice, practice â€" Think of it as muscle memory, similar to an athletes.  It takes work to get better at something.  The more times you run through a song, the better it’s going to get.  It doesn’t hurt to know what you’re going to do with yourself on stage, either.  Practice motions, movement, holding a microphone, and your facial expressions. Be prepared for nerves â€" It can be helpful to know what your voice does when you’re nervous.  Do you get sharp, flat, forget lyrics, or get a crazy wobble?  Prepare for it and know what to do if it happens. Be prepared overall â€" Know what you’ll need at the audition.  Do you need background music or sheet music?  What key are you singing in?  Do you need to dress the part?  Find out as much information ahead of time so you come across as professional. Be yourself and have fun Writers get rejected over and over again, actors wait tables for years before a big break, and singers might sing the same song a hundred times before they find the right audience.  Just remember to love what you sing, sing like you love it, and choose a song that lets your voice shine!

The Rise Of The ACT

The Rise Of The ACT The SAT has predominantly been the staple of standardized tests for students hoping to be accepted into the nations top colleges. However, in recent years the ACT is becoming more popular, according to an article by Bob Schaeffer, public education director of the National Center for Fair and Open Testing, published in The Washington Post. The SAT was created over 80 years ago, and 20 years ago 75% more students took the SAT than the ACT. The ACT was largely a regional test, more popular in the South, Midwest, Southwest and Mountain states. However, most students in the 2010 graduating high school class took both tests. There were very few discrepancies of students who took one test but not the other. Schaeffer argues that the ACT has been marketed more effectively than the SAT, which has greatly increased its popularity. The ACT is more consumer-friendly, and it always had a score choice function, which allowed students to pick which scores were sent to which colleges. The SAT finally implemented that program this year. The ACTbetter represents what students learned or should have learned in their high school classes. Also, the ACT includes a science section, where as the SAT does not. If students do decide to take the ACT instead of the SAT, they can prep by working with a tutor or using ACT practice tests. The ACT also has an optional writing section. The SATs is mandatory. Therefore, students who are not applying to schools that require a writing score can skip the section, saving time and money. Schaeffer argues that this is the most attractive aspect of the ACT. The ACT also persuaded state administrators in Illinois, Colorado, Kentucky, Michigan, Tennessee and Wyoming to administer the ACT to all students. The ACT convinced these state administrators that doing so would increase the number of college applications. The College Board, which is the SATs sponsor, only signed up Maine to administer the SAT to all students. The SAT has also been experiencing many problems. The test was redone in 2005 because of many criticisms, most notably from then-University of California President Richard Atkinson. The College Board then promised to redo the test to make it a more effective forecaster of a students success in college. However, the test-makers own research determined that it was neither an accurate determiner of college success nor a fair admissions tool. Schaeffer writes that there is no significant difference how well the two tests predict student success in their first year in college. In fact, he argues that neither test accurately determines how well a first-year college student will perform. He states that high school grades are and have always been the best predictor for first-year college grades. Both the ACT and College Board admit that their tests do not forecast first-year grades. However, this is the aim for both of the tests. Schaeffer cited Crossing the Finish Line, which was published in 2009. This book considered many different data factors to determine that high school grades are 3 to 10 times more effective at determining college graduation rates. Some colleges are beginning to respond to poor standardized tests by either creating their own admissions test or dropping it altogether and becoming test-optional schools. In the past five years, over 70 schools have taken this route. There are nearly 850 test-optional colleges, according to Schaeffer. [RELATED: What is an Average ACT Score?]
