When did people start using these notes? They
first appeared in the Baroque period. This was a time of
change for composers. They didn’t make music only for
church anymore. They created new musical styles and
techniques. Staccato was one of them. 15
One famous piece that uses staccato is Joseph

Haydn’s Symphony no. 101. People nicknamed it the
“Clock” Symphony because it sounds like a ticking clock.
The sound comes from the repetitive use of short notes.
Franz Schubert’s Military March is another good example. 20

Airbags
American inventor John Hetrick made the first
airbags in 1951. He came up with the idea after almost
having an accident. He remembered something from his 10
time in the navy. He had seen compressed air being used

to shoot weapons underwater. Hetrick tried using the
same system for airbags. When a sensor felt the crash,
compressed air filled the bag. Sadly, at first it wasn’t fast
enough to be effective. 15
Over time, however, people improved airbags. For

example, a man named Allen Breed made a faster
sensor. Airbags are now safe enough for use in cars.
Even now, airbags still keep getting better. Today they can
detect a person’s size and position. Thousands of lives 20
