In music theory, the tritone became known as the devil’s interval. When we write melodies and harmonies, a good number of us probably find that we are drawn, almost instinctively, to intervals such as thirds, sixths, perfect fourths, and perfect fifths. The tritone may be one of the last intervals that come to mind because people tend to dismiss it as a sound that’s tense and uncomfortable to the ear. The tritone, on the other hand, is anything but forgettable; it has a long history and a great deal of potential to convey various emotions, transcending the one-dimensional reputation it has garnered. In this video, we will discuss what a tritone is, its impact on the development of music, and the tritone’s surprisingly sensitive side that isn’t nearly as evil.
