3 and half years I was struggling to train my voice for singing on my entire range. Every time, when i tried to sing, my vocal cords collapsed in the middle of my range. I practiced different types of exercises, vowels, breath exercises. I tried vocal programs like singing success or rock the stage. They helped me for a little, BUT I could not remove those breaks. I accidentally discovered your videos. I found that my main problem is "flip-falsetto" and understand about this problem and solutions. Your exercises helped me remove breaks and now I can move forward to train my voice even more. I would like to thank you master. There are many singers on internet, but only few can call themselves vocal coach. And you sir! You are the best vocal coach, that I found on youtube! Because 3-4 your videos give me more than entire program from others. Greetings from Slovakia.
