Introduction to the Doppler Effect for Sound

Say you were enjoying your favorite band, live in concert. And, they were playing your favorite song. You've listened to this song at home, and know every note. You just love this song!

Guess what: if you got up and started walking around, you won't hear the same thing that you were hearing when you were sitting still! That's right! The sounds of your favorite song won't be right anymore! And, the faster you move, the more "screwed up" the song becomes!

This is what the Doppler Effect is all about. When a sound is played, the precise sound that is actually heard depends on if you are moving or not. In fact, if you want to hear precisely the sound that is being played, you must stand still. As soon as you move, the sound you hear and the sound that's played will no longer be the same thing!
