Resisting the urge to strain
A simple change in mindset can really take you far. As an up and coming singer who is trying to develop power and range in his voice, I seem to have developed a bad habit of trying to push my self harder than I can go. When I first started trying to teach myself to sing higher belting notes, I just started pushing myself. While I did increase my range over enough time with this type of practice, I think it hurt my technique. A few days ago as I was singing some Dio I just told myself to relax into the higher register instead of pushing. Because of the training I've been doing with the program, I think I've been able to increase my range in a healthier way. When it comes to singing the stuff that passes through the passaggio, I discovered a neat little trick on how to improve the technique through those shaky notes. While keeping the throat wide and open, I add distortion from underneath. It's a different type of push than I'm used to thinking of. The voice stays relaxed but there's a certain feeling I pull up from underneath my throat to make the note sound more belted. It's hard to explain. So much of proper singing has to do with making sure your head is in the right place. As Ken emphasizes, you don't want to think of your voice in different registers but instead as one big long note. The idea is that when you get to those weak passaggio notes there is a way to add strength to them in a way that sounds like an "artificial" belt. There are ways to sing higher than your normal range and make it sound natural. The main idea is not to push it in a way that strains. You do have to apply pressure but it's a type of pressure that you're not used to doing unless you train properly. This program helps you develop those techniques.
I'm just trying to say that it takes a long time to overcome a bad habit, and for me the bad habit is trying to belt higher than I actually can. It's better to simply accept what my range ACTUALLY is, and then learn how best to "artificially" sing notes that are higher than that range. If done right you can't tell the difference. Of course, with enough time using Ken's program, you will eventually legitimately increase your range, not just "artificially". But the key point is to relax into your passaggio, not push, because you have to accept that your voice simply isn't physically capable of doing it in the way your brain wants you to do it. There is another way, and it utilizes great technique and produces awesome tone. Maybe I'll make a video describing this technique, because it's not easy to put into words.
