MY BOOK REVIEW 17

"When you speak, sing, or shout, the sound of your voice

moves through the air.

The sound goes to other people, and they hear it.

Sound moves very fast."

Today I read 'Sound And Music'. In this book, the mechanism that sound is made and how we make sound through lip and instruments. As we know, sound is vibration in the air. In our body, sound is made in throat. About instruments, they make the sound made in player's lip loud and release it. I once belonged in brassband club, so this was interesting to me.
