Are all musical instruments tuned equally? For concerts they are. This is
known as "concert pitch," and it's based on setting the frequency of the A
key above middle C to 440 Hz. The frequency of any other note on the
piano, in Hz, is then related to its position on the keyboard by the function
below, where n is the number of keys above or below the "concert A.”
Using this function, can you find the position n of the key that has a
frequency of 55 Hz?*
f(n) = 440.27
