Catona is the BEST!
I also read his book! Its fantastic. I was introduced to his system with the Ultimate Vocal Coach years ago (American Idol beginning) and I utilize this technique in my teaching studio and it works with 100% accuracy! I encourage all my students to download the app for reinforcement when they practice at home. THANK YOU Mr. Catona for your system and this app.
