If you are like most musicians, auditioning for a job is akin to climbing up Mount Everest without oxygen. And, if the audition does not turn out the way you hoped, you probably feel emotionally let down, vulnerable and insecure about your musical abilities. You may even feel like a victim and that you were judged to be “not good enough”. These sort of feelings, although normal and common in musicians, are not helpful to us.
Building your confidence as a musician is key to not allowing your self image to be defined by someone else. One of the most important ways to do that is through regular and productive practicing. So, take out your timer and start practicing! When you do, you will almost certainly find a problem in your playing that need to work on and once you understand the problem and begin working on it your confidence will begin to build and and you´ll start wanting to practice more. Over time, with each problem that you overcome, your playing will improve and your self confidence will build.
I am not saying that this process will eliminate all of your anxieties about auditioning nor will it mean that you won´t feel disappointed if you don´t get a job that you´ve auditioned for. However, as your confidence builds, you´ll find that missing out on a job is not as emotionally difficult as it used to be and that you are able to bounce back from your loss more quickly and begin preparing for your next audition.
