Notes on the above picture: Pythagoras / PUQAGORAS
(569 BC - 475 BC) Greek mathematician and musician. To him we owe the letter
scale notation of A B C D E F G, and the divisions of the octave into the
intervals we still use in western music, indeed the entire scientific
description of musical theory. Pythagoras noticed that vibrating strings produce
harmonious tones when the ratios of the lengths of the strings are whole
numbers, and that these ratios could be extended to other instruments. To
Pythagoras, music was an audible representation of mathematics. He was a
fine musician, playing the lyre, and he used music as a means to help those who
were ill.
