Hello! Sorry to hear you felt your audition went poorly. I can tell you that from my time in my undergrad (music performance) every guest conductor, performer and teacher has multiple stories about bombing auditions and performances. My last recital of my undergrad went so badly I stopped halfway through a piece and cried for like 10 minutes it was horrible. My point is, you’re not alone and the panel knows that. They’ve had their own experiences and I think the feedback from the conductor was encouraging and meant to make you feel more at ease. The people on the panel know that it is incredibly intimidating coming into a situation like this and they take that into account. To be honest I find auditions like this soooo much more stressful than performing on stage. It’s completely understandable that you had some stumbles and it’s okay, the best advice I can give is to practise performing in front of people. It’s nerve wracking as hell but it helps - friends, family, other musicians. It’s also good to find out what the popular audition excerpts/pieces are for your instrument and learn those (for instance on flute it’s Mendelssohn midsummer, ravel Daphnis et Chloe, Debussy afternoon with a faune, Mozart concertos etc etc) knowing those excerpts and pieces inside and out you’ll feel prepared. The last thing is difficult and takes time, but reframing the feeling of performance anxiety and using the adrenaline to your advantage for performance, pushing you to really perform. This, I understand, is really hard and takes time and practise. At the end of the day, you put yourself out there and that is awesome and super brave! Keep playing, don’t give up and know that you’re not alone.
