Mic technique?

start of feature

Like playing the guitar, you aren't going to learn in a day, but there are some simple rules.  The end without the cable goes by your mouth, pointing straight in and pretty close.  OK, so that's an over simplification.  Here are some hints and pointers.  

The microphone has a directional response.  Almost without exception, vocal mics have cardiod or similar response and so will sound great if you talk/sing at the end of it, and will get quieter as you move away from the on-axis position.  Therefore it is important to keep the angle of the mic roughly the same - it doesn't have to be rigid, but once you get past about 45 degrees off, the difference will start to be heard.

The distance the mic is from your mouth changes the sound a huge amount.  While the distance at which you hold it is important, it is variation in this distance that will cause the greater problem.  As you get closer to a mic, a thing called "proximity effect" will mean that the bass is boosted more the closer you get.  Therefore if you suddenly get closer to the mic, it will sound boomy; if you move back off it, it will seem thin.  Also the volume produced changes with this distance.  While good use of distance variation can create excellent dynamic effects and can be used to your advantage, do it badly and it will sound, well, awful.  Much better to change your vocal output controlling your voice than trying to use mic technique until you become confident of what you are doing.

As a starting point, you could do worse than put the mic at kissing distance, i.e. where you could just touch it by sticking out your lips Mick Jagger style.  This means you always stay about the right distance away.  If you have your own mic, or disregard the hygiene issue, put it just touching your mouth - again this makes it easy to keep the distance constant.  

I want to run round the stage with the mic though...

Not a problem.  With a long lead you can jump round like a madman and tie your bass player up in knots all you like.  Handling noise is not really a problem with most decent mics; though clapping with a mic in your hand doesn't produce a good sound.  Problems will probably occur when you copy the people on Top Of The Pops or MTV.
