Alright, it's been about a year now since I started training using the KTVA. My voice has improved for sure, but as for how much it's improved, it's difficult to say. My goals were to be able to sing higher than before. There are three different areas of improvement I want to mention:
First, before I was doing this program, the highest note I could sing in full voice was a B4, which is actually a lot higher than most people who begin the program. A lot of people can only go as high as F#4, so of course they increase their range a ton after they do this program, since there's a lot of room there for growth. For me there is a lot less room, but I have still have grown the voice to some amount. B4 is where my passaggio begins. That hasn't changed; I'm not sure if I could ever expect the passaggio to change where it's located. What I have improved on though, is singing within and through the passaggio. What used to be a B4 for me is now a full note higher; a C#5. The passaggio notes, B4, C5, and C#5, are really a vocal register of their own, at least that's how it seems to me. What I mean is, the voice is always going to get thinner at B4. But that ability to sing in that thin yet full voice has increased by a whole step. So that's good.
Secondly, my highest screams, the mixed voice, has increased. I never remember being able to sing an A5 in full mixed voice. Probably a G5 was my highest. Now it's not that difficult for me. I have on recording me singing an A#5, just about being full mixed voice. Now of course, my falsetto can go higher than that now, though there's really not much use for it overall, since I don't like ultra thin falsetto vocals. But still, I managed to hit a C#6 in falsetto, just to see how high I could get. So both my mixed voice and falsetto voice has expanded by what seems to be about 3 half tones. That's good too.
The last category is the most important category for my personal goals, which is the belting chest voice. I'm pretty sure that prior to the program, the highest I could belt in chest voice was A4, MAYBE on my best day an A#4. This vocal register has increased probably only a half step. During my time recording vocals with one of my bands, on my best days I recorded B4s in full chest belting tone. That isn't on an average day though. On an average day I can belt an A#4 in full chest voice. So on average, this register has only increased a half step. This is where I am a bit disappointed, because for me, this is by far the most important part of my voice I want to increase my range in. Why? Because this is the most powerful vocal register. It is the loudest and most resonant register; the thick, full, operatic voice that I want to build.
My main goals were and still are to increase my range, and now that I'm more familiar with the different types of vocal registers, it's specifically my belting chest register that I want to build and make higher (assuming that it's physically possible, I don't know if it is or not). You see, in Ken Tamplin's scales and exercises, the idea is to sing softly and connect the chest with head voice smoothly. This I have done, and that's great! However, what seems to be lacking in the program is the development of that loud, thick, powerful belting voice. We develop and strengthen the passaggio by learning to roll the chest into the head, with only as much volume as needed to make the connection smooth. But what about training the voice so as to turn those passaggio notes into belting chest notes? I hope that this is possible, because that is my goal. Now that I have built a smooth connection and have experience shifting between the registers, maybe I can train to expand the chest voice in the future.
Now, I should mention that I have not looked at any of the "Pro Packs" yet, and so I have yet to see any of the ways in which Ken applies the vocal workouts in ways that sound good in actual songs. I have seen the Dio videos, and I noticed that he's applying a lot of strength of muscle into the performance which I never hear him doing in the vocal workouts. He does an excellent job covering Dio, and if he can help me develop that same type of singing voice than I would be ecstatic.
I should also mention there are other areas of improvement to my singing in general, such as the use of good support and holding back the air.
So that's my feedback on the program. Comment and let me know what you think.
