Perfect for self taught! Record yourself too!!

I use a lot of YouTube video vocal lessons, I won’t plug them here because it seems inappropriate but they’re easy to find. There’s something about how CVT approaches the voice and different modes that really has helped me place my voice in appropriate places. Personally there’s maybe one or two rules you can bend. You might have to be a little advanced to know when to break the rules laid out, (I’m an ex theater kid) but if you’re brand new, the rules laid out in this course are the healthiest and safest. I love the layout and have no issues with any of that! The print is large enough to read but not so large it’s obnoxious. The pictures and graphs are very detailed. I think the app is very well designed and very visually appealing. This is the first purchase I’ve made towards self teaching singing, because there’s a lot of free stuff out there. But, this is about the same price of one vocal lesson, but will give you months if not more that you can takeaway and perfect. Don’t forget to record yourself practicing!!

Very Detailed

This is an amazing book! So far the methods have helped me progress my voice more than any youtube video. However, there are times when it gets really wordy. I wish the voice demos showed the voice through the scale so I could hear the changes the singer makes from the lower notes to the higher.
I wish it was laid out a little clearer as well. I think the density section isn’t an independent variable so mentioning it does get confusing.
The PDF’s dont allow exiting once you enter & there is no print option.
If you could make a section that simplified all the modes (how to achieve it, how to grow the center of the modes, some practice exercises relevant to the mode ) and had vocal demos for each of the vowels going up the scale, it would help me and lots of other singers out a lot!
Simple DOs to each mode as well would be great - not as a summary section of what it is etc. but you’ll know you’re in the mode if you feel a sensation in spot A...
