Why not just strengthen the specific parts of your voice that need strengthening, while maintaining the solid parts of you voice? Target the weakest parts of your voice, make them mighty!

Each course isn't for specifics, as all these coaches are working toward the same complete goals, so choose the course you feel works best for you and stick to it;)

Okay thanks! I'm really into putting my own vocal workout together to fit my voice. Like I love doing your Isolation exercises three days a week as my workout, then I do the next two days of my workout Ken Tamplin's How to sing better then anyone else course. Will this confuse my vocal cords?

I think Jim Gillette Vocal Power scale exercices are a good complement to RYV. I had quite good results combining both for strenghtening my full voice.

yes, Jim's scales are the only ones I use now, mainly because he called me up last year and handed me over the keys to his training legacy. He said I was the only one he would endorse to teach his scales. So, what did we do? We wrote a book together and created new scales. They'll all be out when the tie is right;)

I'll check out Jim's stuff! How often should I practice a day?

And Also What do you think about Ken Tamplin's training? Should I still add that in to my vocal practicing? I have the volume 1 dvd and he works a lot on Falsetto development.

Don't know anything about Ken's program. I remember one song he had out in Christian metal back in the early 90s. I really liked it:) Jim was my coach so I choose to use his, as well as Elizabeth Sabine's stuff. My other favs are Thomas Appell and James Lugo. Really like Eli Prinsen's program too. Practice is individal. it ay be 30 minutes or two hours a day.
