As a trombone player there is one thing I learned that not only helped me on trombone, but helps me everyday when I get behind the microphone.
It is a free resource for you to use as much as you want. There’s an unlimited supply of it almost everywhere you go.
Air.
Try saying a phrase on half lung capacity and then take a deep breath and use more air when you speak.
What happens? That’s right, your voice sounds more resonant, it carries better, and you have access to more of your range. Plus, if you keep using a good amount of air when you speak, this will energize you, raise your heartbeat, and give you a little bit of a workout. This increase in energy will allow you to focus better and put more energy into your performance, more than likely reducing the amount of takes you’ll have to do to get the copy just right.
The only downside I can see is you having to take bigger breaths when you need to breathe, but that shouldn’t ever be that big of a problem.
That was easy. Hey… where’s my staples button when I need it?
