Real-Life Math -- Solution
To find the frequency of C8, multiply the frequency of B7 by 1.059.
3,951.066
x 1.059 = 4,184.179 cycles per second
Now find the frequency of
C sharp 1:
32.703 x 1.059 = 33.965 cycles per second
And
now find the frequency of C sharp 5:
523.251 x 1.059 = 554.123
Brown
tunes a piano by comparing one note with another. But to get started, he will
check the first note with his electronic tuner or a tuning fork. "Then relative
to that note, I will fairly perfectly tune the piano," he says. "It's called
'perfect relative pitch.'"
Some people think tuners have something
called "perfect pitch," but that's just a catchphrase that someone
dreamed up years ago.
"If someone had perfect pitch, he could tune
A400 -- the first note when tuning -- without a fork or electronic device.
That is simply impossible."
Brown illustrates his point using an analogy.
"Say
you painted a wall and you called me in as a painter and you wanted me to
paint the other wall. You were told that I had 'perfect paint colour-ability.'
Do you think I would be able to mix a batch of blue dye colour #51346? I might
come up with #52000 -- which would be close but not match exactly."
