I've had students with deep voices who thought they could never hit the falsetto area, but with regular scale exercises with me they were able to achieve what they had earlier thought was impossible. If you don't have a vocal coach, or can't afford one -- I know they can be quite costly depending on where you live -- buy a program that has the scales on CD. The only disadvantage with that (working on your own) is that you don't have a knowledgeable person to assist you. You need a second pair of ears. Always.
