Singers need to prepare as much as other band members – but in a different way. Their instrument is their voice and like the instrumentalists it needs servicing, maintenance and tender loving care. The voice is a muscle and also needs to be exercised gently before use. Think of yourself as an athlete who is about to run the 400 metres. You need to warm your muscles up gently prior to the race. If you don’t you are likely to pull a muscle, or hamstring, or even run out of breath!! Prior to singing try some warming up exercises, even talking is an exercise. It is not a good idea to get on the microphone totally unprepared.
Avoid eating certain things before singing as they create saliva and mucous – cheese, milk, apples, chocolate etc. Hot non-milky drinks are OK, as is water, but alcohol is open to debate.
