A "microphone" is a useful music aid. This one might look a little dated now. I'm not even sure what current microphones look like! This one is easy to make though. Use a short piece (about 8 inches) of 3/4-inch dowel. I painted mine with gray acrylic craft paint and then sealed it with a matte spray varnish. Push a 2 1/2-in Styrofoam ball on to one end of the dowel to first make a deep impression in the ball. Drip glue into the hole and push the stick in. Let it dry and then paint the ball black. Twist a short length of a silver chenille stem into an "antennae" and attach to the bottom with a thumb tack. I've seen plastic microphones at the dollar stores also.
I use the microphone mainly when I have a bit of extra time. I'll ask a child (or a teacher or leader) to come forward and will ask them a short series of questions in a "V-I-P Interview". I'll ask about their full name, chores at home, a favorite food, pets, favorite school subject, etc. Just one or two questions and then I ask what song they would like to sing.
There are lots of other ideas for a microphone, does anyone else use one?
