I'll tell you a secret. 99% of those articles in Music category, especially Vocal technique, are shit! That's why they singing wrong and can't progres. I have not found there the DIAFRAGMAL support (only BREATH support, which is secondary or even 4-5-6-dary). That the one and only crucial part in singing, it makes your throat less restrained. 

 Where can I find my article? I have not saved it.
