BI - I'd take another look through the threads - there is a LOT of information on the forum regarding voice training, breathing, etc. Yes - in the long run most people reccomend get a tutor - but that doesn't negate the information presented in the thread. Part of the reason to get a tutor (or at least a knowledgable musical director - such as in a good community choir) is so that you have an outside viewpoint to prevent your developing bad habits.
