Music affects the heartbeat, pulse rate,
and blood pressure. It's pretty obvious how this works. From the previous
paragraph where the breathing was affected, it's nearly the same thing.
The heartbeat responds to sound and music just as we would. It picks up on
the frequency, tempo, volume, and it tends to speed up according to the
pace of the music. It's not necessarily going to go with the beat, but it
will slow down or speed up to a fast or slow song, but only within a
certain range. Because the heart can only go so fast or so slow and still
be safe, and it sure wouldn't kill itself. Just like the breathing rates
in the last paragraph, the slower heartbeat makes it so the mind is calm,
it reduces stress and tension, and helps the body heal itself. There are
studies on this particular statement, but nearly all the studies are the
same. Two groups do one thing, one is exposed to either silence or a
neutral music, and the other to the music you're trying to prove something
for, and it comes out positive for the hard rock, or the elevator music,
or whatever music one may have tested. The heartbeat, affects the pulse
rate, because they're related, so that's how it affects the pulse rate.
Music can change the blood pressure also. �Dr. Shirley Thompson, an
associated professor of epidemiology at the University of South Carolina
School of Public Health, reports that excessive noise may raise blood
pressure by as much as 10 percent.� It's not likely that all the types of
music you listen to will raise your blood pressure until it's unhealthy,
these are just minor changes that don't really mean anything; it just
shows what music can do to our body. (Campbell 67)
