This is a difficult question... a lot depends on what instrument you play and how many other applicants there are for each section. Every year we accept a large number of new members to the orchestra and we always name alternates.
DO NOT be intimidated about auditioning! Our auditions are actually pretty low-key (seriously! see the next question), and you’ll never know unless you try... we want everyone who has considered playing for HRO to audition with us!!! This year, we accepted around 30 new members!
