Fun Science Sound

C                 G          Eb 
It starts with an idea or an 
               F
impulse to make a sound,
           C                 G    
And then a message gets sent to my
               Eb              
 head where my vocal chords are 
 F
found.


       Bb                     F   
And they vibrate, and cause the 
           C
air to vibrate too.
         Bb                     
Then the air gets shot out of my 
F                    G
mouth on its way to you!


C              G           
This vibration I've just made 
   Eb           F
travels as a wave,
       C          G               
But if I vibrated differently then
          Eb                F
 it would cause the wave to change.


          Bb           F          
If I sing low then the frequency 
           C
of the wave drops.
          Bb            F
If I sing high then the frequency is
 high too.
And if I sing loud then my 
             G
micro-phone pops!

    C                  G          
The sound wave travels through the
     Eb               F
 air unless it hits a wall
         C              G     
Then the higher frequencies get 
                  Eb             
absorbed and the deeper ones pass 
   F
through


               Bb               
And that's why when I'm behind a 
 F                   C
window I sound like this.
           Bb              F      
And if the wall is hard the sound 
bounces back and you can hear an 
G
echo!


             C             
The sound is captured by my 
 G               Eb              F
micro-phone and sorted digitally,
           C                 G    
That was until you play this video
              Eb                   
 and now your speakers are 
 F
mimicking me


            Bb                  F 
And now the waves are back and 
              C
going into your ear.
            Bb                     
Only 6 more steps inside your head 
                  G
until you get to hear!


C        G          Bb
Sound is touch at a distance,
F                  C         G  
When they say that music can 
            Bb         F
touch you, it literally does.


C        G        Bb
Sound is a vi-ber-ation,
    F                C       G   
But thanks to modern science we 
                 Bb
can know that it's shaking our 
eardrums:


Bb
And the drum then shakes some tiny 
bones
C
And the bones send vibrations to a 
liquid
Bb
And the waves in the liquid bend 
some hairs
C
And the hairs send a signal to the 
brain
Bb                          
And it's only when it forms a 
                  C              
pattern in your head that you can 
   G
hear!
