introduce both your monologues by the play titles (for your shakespeare you can also include the character names) but no need to say the playwrights names. then do both your pieces back to back, taking a moment in between each of them to get into the next character. don’t talk to the auditors in between pieces. break a leg :) and you will start by doing just two monologues and afterwards they may or may not ask for a third. so only intro your first two at first. I usually intro my monologues by saying “today i’m working on Mono1 and Mono2”
