At the new Museum of Mathematics (MOMATH) there is an exhibit called the Harmony of Spheres. As you touch the spheres in this exhibit, they light up and emit three notes to create a chord. As you move around, the notes shift up and down in half-steps—sometimes resulting in harmony, sometimes resulting in dissonance. You can explore the world of music and look at it in a mathematical way, as the relationship between the chords.
Pythagoras was the first to identify that the pitch of a musical note is in proportion to the length of the string that produces it, and that intervals between harmonious sound frequencies form simple numerical ratios.Common sayings such as “the harmony of the spheres” and “it is music to my ears” point to the notion that music is often ordered and pleasant to listen to. And at MOMATH it’s also fun to explore.
