ly at the mouthpiece, you see a tiny piece of
rubber tied across it. The air rushing past this rubber is what makes
your balloon sing.
Your own music box is made on the same plan. When you breathe out, the
air is pushed from your lungs up the pipe that we call the windpipe.
In the upper part of this is the little box, a corner of which you can
feel with your thumb and finger. Across the box, inside, are stretched
two folds of skin and muscle, just as the rubber is stretched across
the opening of the balloon. Whenever you like, you can blow out your
breath between these folds of skin in your voice box. Blow it out in
one way, and what happens? You are singing. Blow it out in another
way, and you are talking; in still another way, and you are just
making a noise--perhaps mewing like a kitten, or neighing like a
horse. If you pull these folds of skin close together, you can close
your windpipe and "hold your breath." A cough is made by filling your
chest with air, holding the folds close shut, and then suddenly
"letting go." How many sounds you can make from one tiny music box! Of
course the muscles of the mouth and throat, and the teeth and the
tongue all help the voice box as much as they can.
One of the best ways to keep your voice clear and strong is to dash
cold water every morning on your throat and chest, then to rub with a
coarse towel till your skin is pink and warm. Gargle your throat with
cold water if your voice is husky. Singing is very good for you, too;
but don't try to sing too hard. Sing easily and gently, and see how
many words you can sing without taking a breath. That is good for the
lung-bellows as well as the voice box. Always sing in fresh air, but
not in cold air.
When you talk, try to make all the words clear and distinct; open your
mouth and let the sound out. Once I had a big grown boy in one of my
classes who did not open his lips properly when he spoke. So I asked
him to prop his mouth open with a piece of stick and then talk. I made
him do it until he learned to speak much more clearly. A famous Greek
orator, named Demosthenes, who had a habit of mumbling his words,
trained himself to speak clearly by putting pebbles in his mouth and
then reciting in a loud voice.
When you want your voices to sound pleasant,--and that is always, of
course,--you must call on your brain to help. That is your thinking
machine. Always think twice before you let anything unpleasant or
unkind come out of yo
