Basically what I said in the title? So do you think a singer can be amazing from technique or do you think its more of a natural thing such as certain resonating sinus cavity.

My guess is that Jaime V. is gonna say yes - it is absolutely positively possible for anyone to develope a great voice with good technique if they want it bad enough and practice hard enough. If I'm right, I win 32 thousand dollars...

you have to ask yourself what makes a great singer to answer that question, it is very largely subjective, but most would agree that great singers sing with lots of overtones, which can be taught.. so, my answer would be, yes.

In my opinion, if you talk about the tone quality (not the range)of the voice thats something that comes from the resonance in the sinus.

An amazing and dedicated person makes an amazong singer. For me to say that this technique would make anyone an amazing singer would just be some schmuck trying to sell a book. I can say that this technique can create a better vocal instrument for anyone who applies the techniques and exercises.But to become an amazong singer invlolves so many facets to the production of the voice, that it is up to the individual to make that journey:)

When i watch a singing i judge them on their singing, and their voice which are completely different things. I have heard singers who have incredible technique, so their singing is amazing, but the sound of their voice is bad. And then the other way around where some people have incredible sounding voices, but have no technique, and no range etc
So personally i think that not everyones voice can be amazing, even if they have the best technique in the world.

how you like the sound of the voice, lee, is based on your opinion, other people will probably think that same singer is good

An amazing voice is a matter of opinion. If this weren't true, we wouldn't have thousands of singers in different genres with millions of fans. It is personal taste of that listener's ears. That's how Bob Dylan made it ;)
