Problem: The Pythagorean Comma
There are several ways to explain the Pythagorean comma. In a nutshell
you cannot tune a circle of Pythagorean 5ths and end up where you started.
Start from C and tune perfect 5ths all the way around to B#. You will find that C and B# are not in tune.
702+702+702+702+702+702+702+702+702+702+702+702= 8424 cents
A half step is divided into 100 cents. There are 12 half steps to an octave. Therefore, an octave is 1200 cents.
1200+1200+1200+1200+1200+1200+1200= 8400 cents
8424 - 8400 = 24 cents = Pythagorean Comma
Result: From the 17th century to the present, the music of the Western Hemisphere has used Equal Temperament, created by lowering the perfect 5th from 702 cents to 700 cents.
