Credit: PNAS, doi: 10.1073/pnas.1324142111 Physicist Holger Hennig, currently with OptWare in Munich, Germany, has developed a stochastic model to describe synchronization that occurs in human musical rhythms that involve more than one person. In his paper published inProceedings of the National Academy of Sciences, Henning describes how he discovered that when two musicians are playing together, a beat played by one person can depend on up to several minutes of the other person’s prior interbeat intervals—the model he developed can be used, he claims, to produce more natural sounding computer generated music. Most people can tell when the music they are listening to is backed by computer generated sounds, whether percussion, stringed instruments or even other beat setting implements—it just sounds too “perfect” to the human ear. For that reason, scientists have been searching for ways to introduce less perfection, to fool the listener into believing they are listening to music created exclusively by humans (because most people prefer it that way).
