• Twelve-Tone Musical Scale. Why does our musical scale have twelve notes (counting both the white and black keys on the piano)? Why not ten or fifteen or twenty? The answer is: The twelve-tone equal-tempered scale is remarkable. The nearly perfect intervals seen in the table above are not typical of other equal-tempered scales. The twelve-tone equal-tempered scale is the smallest equal-tempered scale that contains all seven of the basic consonant intervals to a good approximation—within one percent. Furthermore, for the most important intervals, the fifth (3/2) and fourth (4/3), the approximations are better—within about one tenth of one percent.

Notes

• Everything is a Remix. Creativity isn't magic. It happens by applying ordinary tools of thought to existing materials. And the soil from which we grow our creations is something we scorn and misunderstand eventhough it gives us so much and that is "copying." We need copying to build a foundation of knowledge and understand, and after that things can get interesting.
