There are probably fewer singers than even bass players who have had any formal training in their chosen discipline, and thus do not have the technical know-how as to how to use their instrument (the voice...). [i]Good [/i]singers can, indeed, choose the range in which to perform, and match their voice to the song (within limits, naturally...). Lessons would solve most, if not all, the issues one has with many singers, I reckon, but try convincing some of 'em of that..!

You're absolutely right. At uni the vocalists used to spend ages going through warm up exercises before singing. They would never just get up and grab a mic.
