Air from he lungs quickly passes trough the tightened chords, create them to vibrate. The vibrations make the sound of the voice. The tighter the chords are, the smart the vibrations and the higher the resulting sound.

If a oscillate is thrown onto a pacify pond, several turn overs travel out from the place where the oscillate hit the surface. Likewise, sound moves in waves through the air or some other strength. The understanding that sound travels in the image of waves may have originated with the artist da Vinci Da Vinci in 1500. Generally, waves can be sprinkle transv ersely or longitudinally. In both cases, onl! y the energy of wave motion is spread through medium. No portion of the medium actually moves very far. As...
