Hey all, I had bought a vocal coach kind of computer program, where it first discovered your range, and then slowly introduced intervals within that range, and it taught proper breathing and warm-ups and things like this. Unfortunately, I needed a new computer and this program wasn't able to work with Windows 7. So I need a newer one. I don't mind paying for it, but hopefully not a lot, I don't have the cash right now for private lessons. Anyone know of any good ones? Thanks.
