People and animals use various forms of sound to communicate their thoughts. Sounds are a vital to our being. We use sounds to communicate thoughts and to learn and convey ideas and express our feelings. This may be done face-to-face or with a telephone. Musical sounds affect our emotions, making us happy or sad, agitated or relaxed. In this book you will learn how sound and sound waves travel. You will make and design your own drum, guitar, recorder, maracas, and various pipe instruments. Fine-tune your instruments for that perfect "pitch", "frequency" and "volume". Create stereo sounds.
