Sound Waves & Phonation
"It is true that we do not have conscious control of all of the actions of the sound waves, but sensitivity increases in direct proportion to receptivity--you cannot control what you are not aware of." - Arthur Lessac
An internet tutorial site for high school students provided by Glenbrook South High School in Glenview, Illinois. General information about sound waves with information about how sound waves work in musical instruments.
Easy to understand explanations about how sound waves are formed, as well as clear descriptions about velocity, frequency, amplitude, etc. This site also has a mini-quiz to test yourself after you read the sound wave information.
Paul Flavin has created an interactive piano keyboard that you can play to see how sounds waves behave. You don't need any download to do this because a Java aplet is built into the page.
Wikipedia gives a very detailed description of phonation, which can get tedious if you're not ready to spend a lot of brain work trying to sort everything out.
Paul Mason, a teacher from Canada, explains in simple terms just what phonation is all about.
What's An Oscilloscope?
Answer: an electronic instrument to measure sound waves, electrical signals and other wave forms and display them as graphics. It comes from the word oscillate, which means to move back and forth or vibrate. Sound waves are oscillations.
