This would certainly be interesting, and it would be a great idea on Digital DJ Tips’ part!
But in my opinion, it can also be learned easily at home. I know there are a handful of people who don’t enjoy listening to their own voice, but the following advice is great practice.
I recommend picturing an audience in your room, and just talk to yourself – your imaginary audience. This will give you more confidence and ‘comfort’ using the microphone.
It also helps a lot to, before a gig, write down things you would like to say to your event. This helps me a lot personally.
In mobile DJ’ing, your MC abilities are very important for success. In fact, most of my mobile DJ gigs are mostly mic-action and less mixing action.
Hope this helped!
