What is Relaxation Response?
I hear Mr. Tamplin saying that relaxation response is necessary to reduce strain in higher notes. I'm am trying to strengthen upper chest voice notes right now (I am tenor; belt range starts at D4) and I have heard the relaxation response reduces strain when coupled with other techniques of course (diaphragmatic support, slight vowel mod). Can someone explain to me what relaxation response is? Any help will be greatly appreciated.
