What is Pitch?
Pitch is how high or low something is. It comes from the Greek mathematician Pythagoras who found that a longer string makes lower pitch than a shorter string. How thick, thin, more relaxed, and tight something is affects their pitch.
What is Volume?
Volume is how loud or soft a sound is. The amount of energy in a sound wave depends on how loud or soft it is. You can increase the volume by vibrating more of the surface. A loud sound has more energy than a soft sound and has a taller sound wave.
How do you Measure Pitch and Volume
Pitch is measured by a oscilloscope. The machine takes a picture of the sound waves. It let's you compare and contrast the sound waves. Frequency is measured in units called hertz. Volume is measured by also an
- scilloscope. Volume is measured in units called
decibels.
High Pitch vs. Low Pitch
Let's say we have a string. If the string is short it vibrates faster and has a higher
- pitch. If the string is longer it produces
a lower pitch. High Pitch Low Pitch
Loud Volume vs. Soft Volume
Let's say we have a rubber band. If you pluck the rubber band harder then normal it's louder. How loud or soft the sound depends on how much energy is in the sound waves. You can also increase the volume by making more of the surface vibrate.
