Hey Qualona. I did my viva voce in 2005. We also had to do them in year 11 (2004). Specify exactly what you have to do for the viva voce... the actual meaning of a viva voce is basically a talk... question and answer. That's what we did for year 11. But year 12, we basically had to give a presentation... not exactly on Blues, but that's beside the point. It shouldn't be too hard talking about blues. Make sure you have plenty of foundation info about it, artists back in those times, recordings, characteristics of Blues etc etc. Make sure it's well structured. As you can see, I am suggesting this stuff on the basis on a viva voce being a presentation. Tell me if that's not the case. It's basically you teaching a class... for... 10 minutes? So not too long. Hope this vague reply helps. If you want to have a look at my presentation, let me know and I'll email it to yah.
