Try picturing a note and carefully as you exhale, bring it up from the point at the abdomen where in you center your breath like a baby and not from your vocals area. especially a note you do not hear. If we cannot hear a certain frequency in our ears, we will not be able to vocalize that frequency in our throats. (I found this out while experiencing my health problem this past year and as my singing voice was affected, I had to use a practice of trying to form a note mentally and bringing it through verbally to the right pitch and tone..., very difficult when your hearing is having a problem as well as your vocal cord.) This is what Dr. Alfred Tomatis (1920 – 2001) learned studying opera
singers. Though their vocal capabilities were fine, some singers were having trouble hitting notes that had previously been easy. They wanted to know why...., the middle ears of the singers had
become flabby, a kind of "callus" had developed to protect the eardrum from extended exposure to loud noises.As a result the singers lost the ability to sing the notes blocked by this "flab" in their ears. To cure the ailment, Tomatis developed a sound therapy in which music switched on and off in fast repetition. Try this website for cool vibrations
