When l go in at my time slot, what do l do? Should l act a certain way?
How do l start my monologue? Do l just say ''ok here l go'' and then start out of nowhere? l do not wanna mess up. And then how do l end it? l do not just go like ''It is too hard a knot for me t' untie... ok I am done?'' right? Is there a RIGHT way to do these things?
(l mean act a certain way as in before and after my monologue)
:/ But what do l do after my last line?
l do not just walk off all silent, do I? Would not that be kinda weird?

Walk on stage like your diana ross, light it up with a kind smile, take a deep breathe and look em right in the eye if you can, believe in your self, pretend there is spotlight on you and all you can see is blackness if that helps, dont pause, or say anything else. Act as if you did great at the end and walk off humbly even if you think it wasnt as good..

Ok, the last person to answer this question clearly did not understand ur question.

You should learn what is called a ''slate'' which is where u introduce yourself & the piece or pieces u r going to perform for ur auditioners.

Usually it looks something like this;

Hello, my name is ____ & l will be performing the role of ________ from _____.

Then, u take a moment, or two to prep & u enter into ur monologue or song, or whatever u r going to do.

If u r singing, u should give ur accompanist a nod to let him/her know that they should begin, or give u a pitch, etc.

After ur last line, let the final moment hit u & ur auditioners, lift ur head up, smile, say thank you, & walk out of the room.

Hope that helps, & break a leg!
