4. HOW I THINK IT WORKS
As you turn the crank on the bottom it winds up a spring inside a metal cap.
The spring then unwinds turning a series of gears that turns a metal drum.
The metal drum hits against the little prongs, called a pitch comb, and sends
the noise through the air to the ears making sound. Which together all of the
notes sound likes a song.

7. SOME HISTORY
In late 19th century, Germany thought of an idea of small music boxes
The idea wasn’t made into reality until WWII where Japan used some of them
to boost moral for some soldiers.
The Germans got the idea from 15 th century bells being rung by a metal
cylinder and pins.
In Paris, France, the music box was formed into the singing of birds
Japan expanded the idea making more tunes into music box
They used the drum method and used pitch combs
