  1. 1. Sound Energy
  2. 2. What is sound?  Sound is – A form of energy made by vibrations. – When an object vibrates it causes the air particles around it to move. – These particles bump into particles close to them and this continues until they run out of energy.
  3. 3. Try this:  Put your finger on your neck and say “aah” as loud as you can.  Now  You say it as soft as you can. can not only hear the sound, but you can feel the vibration inside your throat.

  5. 5. What is pitch?  Pitch is how high or how low a sound is.  This is a high pitched sound.  This is a low pitched sound.
  6. 6. How does sound travel?  Sound passes through the medium as longitudinal waves.  When the vibrations are fast you hear a high pitch. When they’re slow, you hear a low pitch. High Pitch Low Pitch
  7. 7. How else can we change sound?  We can make it louder or softer by changing the amplitude of the height of the wave.  The higher the amplitude, the louder the sound. The lower the amplitude the softer the sound. Louder Softer
  8. 8. How do musical instruments create sound?  It depends on the type of instrument. There are four types. – – – – Woodwind String Percussion Brass
