For each round, you should bring at least three audition pieces, of which: 

all should be opera (no song or oratorio) 
at least two languages should be represented 
at least one should be in English 
at least one should have been composed post-1970

You may, if you wish, bring additional arias (up to a maximum of 5 audition pieces) from which the panel may choose. You are welcome to bring a post-1970 English aria. 

The panel may stop you during the performance of a particularly long aria so that they can hear another audition piece. 

One month before your audition, you will be contacted by the auditions administrator who will ask if you are bringing any unusual or ‘non-mainstream’ repertoire to your audition. This will be your opportunity to send a copy of this repertoire, to be passed on to the audition accompanist.
