Training FAQs for Singer Applications Who will accompany the audition? The NOS will provide a highly qualified and experienced accompanist for all auditions. This is for the sake of consistency and to serve all applicants to the best of our ability, equally and without prejudice. There will be no opportunity to rehearse with the audition accompanist.
