Singing and Speaking
When you sing, you are a musical instrument. When you speak, you are not. Singing and speaking are different, even though you make the sounds in similar ways.
You sing and speak by making your vocal cords vibrate, or move backwards and forwards. These cords are a pair of small, stretchy bands in your throat.
When you are not singing or speaking, your vocal cords relax. Your breath goes in and out between the vocal cords without making them vibrate.
When you begin to speak, small muscles in your throat pull the vocal cords tight. The air you breathe out makes the vocal cords vibrate. This vibration produces sounds. Your tongue and lips make the sounds into words.
When you sing, your vocal cords vibrate in the same way, but at a different speed. To sing high, your vocal cords tighten. This makes them vibrate faster. To sing low, your vocal cords loosen. This slows the vibrations. So your vocal cords vibrate at exactly the right speed for each sound. Your voice is making music!
