As part of my singing lessons, I have been taught warm up exercises. One starts with me making a sound rather like an older person snoring lightly while he or she naps. From there I am supposed to sound like a old hand-cranked siren getting ramped up, heading up into my “head voice.” I then reverse direction and drop my voice into the, “Luke, I am your father” range.
Another warm up sounds like a cat food commercial. Do you remember the food, “Cats ask for by name?” Meow and Mee-ow up and down the scale. I watch myself in a mirror making vowel sounds. My coach talks about the physical aspects of singing, which is surprisingly helpful. Surprising to me anyway. For me whole lot of learning to sing is learning and practicing the physical requirements.
Then there is the activity in which a single breath powers five descending but discrete consonants followed by a sustained note. Sometimes it does and other times it does not.
At the moment I am trying to voice the vowels ah to i (as in it) to e (as in bee) moving only my tongue. I can more nearly successful when I start with the e and then move to i and finally ah. I haven’t achieved more than an occasional success but I am tired of sticking my tongue out at my reflection in the mirror.
