If you are reading this with an interest in purchasing KTVA, then you will get an honest opinion of the program from someone who has been doing it for 2.5 years, and who took a personal Skype lesson with Ken.
As a person in a band who was scouring the city for male singers with a high range (and having no luck), I took it upon myself to learn how to sing. I stumbled upon one of Ken's YouTube videos, and after seeing some of his student’s videos online I decided to take the dive and purchase the program. I purchased the 3 volume bundle, and started on Vol. 1, putting in 5 days a week, 1 hour per day of singing with the program, and switched volumes after doing each for 6 months.
I can say with confidence that this program is a phenomenal starting point for someone who has little experience as he guides you through the exercises and gives you a solid vocal workout schedule for strengthening your vocal chords muscle memory.
Your voice will get stronger, and change with time as your range expands. My range has since doubled (actually more than doubled) and with that comes other disciplines one must master & be aware of, like proper diaphragmatic support and vowel modifications, which he teaches. I thought that you had to be born with high vocal range, but I was wrong. You can develop it!
The online forum is a great way to check if you're on track with the exercises if you're unsure of your technique, or have questions about virtually anything related to singing. I have found the forum to be incredibly useful, and the staff moderators are very helpful and quick to respond. Even from sifting through old posts chances are you can find an answer to a question you're looking for.
My Skype lesson with Ken was great, he can answer or help clear up questions about issues you may be encountering if you feel you can't get your answer through the forum. Depending on what you want to work on he will tailor the lesson to you. With me he ran the scales to check if I was modifying my vowels correctly. You will get a recorded version of the lesson afterwards to review things you may have missed. He is a cool dude. I found the Skype lesson to be worth it, as I got a good idea of where I currently stand vocally, and what I need to focus on. I would say get a Skype lesson once you have been doing the program for a little while, as he will probably give you information contained in the volume you are on, but if one on one works best for you then go for it!
KTVA is worth every penny hands down. As someone who had zero singing experience it has given me a great path to follow. I've been able to record 2 albums, played at festivals and have gone on 3 tours across Canada with my band because of it. I still have a lot to learn, and have areas I need to work on, but it's all part of a growing and learning process, which comes with any type of skill development.
I'll post a video below of me singing.
All the best to all of you, and good luck on your vocal journey!
