The mathematics of music isn’t as simple as you might think, and early musical instruments often didn’t get it right. Keyboard instruments were especially susceptible to this. On a particular organ, for example, the fifth interval in the key of C might sound harmonious, but the fifth above Ab might be sour and grating to the ear. These so-called “wolf” notes could spoil a whole composition. It wasn’t until the late 17th century that “well-tempered” instruments came along, a fact that was celebrated by J.S. Bach in his solo keyboard composition, “The Well-Tempered Clavier,” which includes harmonious preludes and fugues in every possible key.
Like notes on a piano, web parts (or any kind of web widgets) are combined in new and unexpected ways on a page. Yet sometimes they don’t play well together. This article will show you how to write “well-tempered” web parts that always behave appropriately, even if other versions of Angular are used on the page.
