Questions
to be pondered:
|
Since music is
made up of combinations of sine waves, what instrument
do you think can produce a graph that is the closest
to the standard f(x)=sin(x)? (Another way to think about
it: What instrument produces the purest tone?) |
| What instrument
do you think would produce the most complex sine waves? |
|

The instrument that produces
the purest tone (a wave closest to the standard sine wave)
is the flute!
Here's a zoom-in
so you can see what's really going on!
Note: If you consider
the range of instruments used in Hillbilly music...... then
the bottle really gives the purest tone! Check it out!

(Please ignore the fact that this picture says "flute"
-
It's really a bottle!)

 |
If we zoom-in,
we can see what a perfect sine wave blowing into a bottle
can produce!
| What instrument do
you think would produce the most complex sine waves? |
The instrument that produces
the most complex sine wave is the cymbal! (Or the human voice,
if you don't consider a cymbal an instrument.)
Look how messy
this zoom-in is!
