First and foremost, you need to enter an audition knowing you deserve it. If you can’t muster this kind of determination and confidence, you’re doing yourself and your talent a disservice and those listening to you will be able to hear how unsure you are in your voice.
Now, don’t think I’m telling you to be cocky because there is nothing worse than somebody coming off as arrogant — especially in an audition situation. If you want to put off everyone in the room immediately, act as if you’re too good to try out or like you don’t need whatever role you’re attempting to win.
You should not just convey but truly believe you are worthy of winning when it comes to this audition. The prize may be a spot at a college, a scholarship, or maybe an actual job, but what’s at stake isn’t the biggest concern. If you want it, you need to feel like a proper fit.
While that can be really difficult to do sometimes, especially when you’re up against other talented singers or if you’re still new, many people who end up nailing auditions do so because they believed in themselves and what they had to offer.
